How to Install Intel Graphics Driver version 15.4251 If you are a PC gamer or a content creator, you may have encountered a specific error message when launching games like Need for Speed (2015) or Need for Speed Heat stating that a driver update to version xx.xx.15.4251 or later is required. This version is often cited as the minimum requirement for stability in titles that utilize the Frostbite engine on older Intel hardware.

Whether you are looking for the modern 31.0.101.4251 equivalent or the legacy 15.40/15.45 series, this guide provides a step-by-step process for a clean and successful installation. Why You Need Driver 15.4251

Graphics drivers act as the translator between your operating system and your hardware. Installing this specific version or a newer one can:

Resolve Game Crashes: Many older titles require version 4251 to avoid immediate crashes upon launch.

Enhance Performance: Newer versions often include "Day 0" patches for modern games and performance tweaks for existing software.

Improve Stability: Updates resolve known bugs such as visual artifacts or application hangs in software like Watch Dogs: Legion or Topaz Video AI. Option 1: The Automatic Method (Recommended)

The easiest way to ensure you have the correct driver for your specific processor is to use the Intel® Driver & Support Assistant (IDSA). Intel® Driver & Support Assistant intel driver xxxx154251 install

The request for driver version xx.xx.15.4251 is a common prompt encountered by PC gamers, particularly in titles like Need for Speed Heat or Plants vs. Zombies: GW2. This specific version number often acts as a minimum requirement baseline for Intel Integrated Graphics.

To complete this "feature" or requirement, follow these steps to ensure your drivers are correctly installed: 1. Identify and Clean Existing Drivers

Before installing new software, it is often necessary to remove corrupted or outdated versions.

Access Device Manager: Right-click the Start button and select Device Manager.

Locate Display Adapters: Expand this section and right-click your Intel(R) HD/Iris Graphics.

Uninstall: Select Uninstall device, and importantly, check the box for "Delete the driver software for this device". 2. Install the Required Version

Since "15.4251" is an older driver baseline, you have two primary ways to satisfy this requirement:

The Intel driver version (often part of a full version string like 15.40.xx.4251 or 20.19.15.4251) is a legacy graphics driver typically used for older Intel HD Graphics on Windows 7, 8.1, and early Windows 10. Intel Community Quick Installation Guide

To install this specific driver version, follow these steps: Uninstall Current Drivers Device Manager (right-click the Start button and select it). Display adapters , right-click your Intel Graphics entry, and select Uninstall device

Check the box for "Delete the driver software for this device" if prompted. Download the Installer Intel Download Center

Search for your specific processor model or "15.4251" to find the version compatible with your operating system. Run the Installation Locate the downloaded file and run it as an administrator. Follow the on-screen prompts. If available, select "Execute a clean installation" to ensure all old driver files are replaced. : Reboot your computer to finalize the changes. Alternative: Automatic Update If you aren't sure which version your hardware needs, the Intel® Driver & Support Assistant (IDSA)

can automatically identify and install the most appropriate driver for your system. Troubleshooting Tips OEM Drivers

: If you have a laptop (e.g., HP, Dell, Lenovo), your manufacturer may have a customized version of this driver. Check their official support page first to avoid losing manufacturer-specific features. Verification : After installation, go back to Device Manager Display adapters Properties tab to confirm the version number is correct. Intel Community

Intel Graphics Driver version 31.0.101.4251 is a WHQL-certified release designed to optimize performance for Intel Arc A-Series Graphics and Intel Iris Xe Graphics. Installing this driver ensures your system remains compatible with the latest games and creative software while fixing known stability issues. This guide provides a step-by-step walkthrough for a clean installation and troubleshooting common errors.

Before beginning the installation, verify that your hardware is compatible. This driver version primarily supports 11th, 12th, and 13th Generation Intel Core processors with Iris Xe graphics, as well as the discrete Intel Arc GPU lineup. Operating system support is limited to 64-bit versions of Windows 10 and Windows 11.

To start the process, download the official installer directly from the Intel Download Center. Avoid third-party driver update sites, as these often package malware or outdated files. Look for either the .exe installer for an automated setup or the .zip file if you prefer a manual installation via Device Manager. If the package contains INF files (driver files):

For the most stable experience, many users prefer a "Clean Install." This removes older driver fragments that can cause flickering or crashes. To do this, run the installer and look for a checkbox labeled "Execute clean installation" during the setup customization phase. If your system is currently experiencing heavy graphical glitches, you may want to use a tool like Display Driver Uninstaller (DDU) in Windows Safe Mode before running the new Intel installer.

Once the installer is running, follow the on-screen prompts. The screen may flash black or change resolution several times during the process; this is normal as the system swaps the old display architecture for the new one. Do not restart or shut down your computer until the installer explicitly confirms that the process is complete.

After the installation finishes, a system reboot is highly recommended to finalize the registry changes. To verify the update was successful, right-click the Start button and select Device Manager. Expand the "Display adapters" section, right-click your Intel GPU, select Properties, and check the Driver tab. The version should now reflect the 31.0.101.4251 build.

If you encounter an error message stating "This driver is not validated for this computer," it usually means your laptop manufacturer (like Dell or HP) has locked the driver to their specific versions. You can often bypass this by manually installing the driver through the "Have Disk" method in Device Manager, though it is generally safer to wait for the manufacturer-approved version if you are not experienced with manual overrides.

Updating to driver 4251 provides significant "Game On" support for new titles and improves frame delivery in DirectX 11 and DirectX 12 environments. By keeping your Intel graphics software current, you ensure the best possible balance between visual fidelity and system reliability.

The driver reference xx.xx.15.4251 is a legacy Intel Graphics driver version that gained notoriety primarily as a strict "minimum requirement" for modern games like Need for Speed Heat and Plants vs. Zombies: Garden Warfare 2. The "Informative Review"

If you are being prompted to install this specific version, you are likely dealing with a legacy Intel system (typically 6th to 10th Gen Intel processors) trying to run games that utilize the Frostbite engine or similar modern APIs.

Reliability: For its time, it was a stable milestone. However, in 2026, it is considered an "ancient" baseline. Its primary purpose today is to bypass "Driver Version Error" pop-ups in older EA games.

Performance: It does not offer modern optimizations (like those found in Intel Arc drivers), but it provides the necessary instruction sets for basic 3D rendering in titles that would otherwise crash at launch.

The Conflict: Many users with newer hardware (like 12th Gen UHD 730) mistakenly see this error because the game's "check" is poorly coded and doesn't recognize that a newer driver is actually better. Installation Best Practices

If you must install this version to fix a game error, follow these steps to avoid the common "Installation Failed" loop:

boxRoundCorners - 'all' | 'top' | 'none'
Enables round corners on all box corners on the outside of the floatbox frame area, on just the top two corners, or 'none' disables all outer round corners (and you get square ones).

boxCornerRadius - pixels (10)
When box round corners are enabled, this defines the outer corner radius in pixels.

contentRoundCorners - 'all' | 'top' | 'none'
Enables round corners on all content corners on the inside of the floatbox frame area, on just the top two corners, or 'none' disables all inner round corners (and you get square ones). The default setting is effectively 'none' because the default contentCornerRadius is 0. Round content corners are available only for browsers that support CSS round corners, and so will not be drawn in IE 8 and earlier.

contentCornerRadius - pixels (0)
When contentRoundCorners are enabled, this defines the inner corner radius in pixels.

shadowType - 'drop' | 'hybrid' | 'halo' | 'none'
Set 3D shadow effect. 'drop' sets a 2-sided shadow on the right and bottom. 'hybrid' sets the full shadow on the right and bottom and a fainter half shadow on the left and top. 'halo' sets a full shadow on all 4 sides.

shadowSize - pixels (10)
Sets the width in pixels of the shadow effect around the box.

shadowOpacity - 0-1 (0.4)
The opacity or darkness of the shadow effect around the box.

outerBorder - pixels (1)
Width of the border around the outside edge of the box. If round corners are being used, the outerBorder size will not exceed the corner radius.

innerBorder - pixels (1)
Width of the inside border around the edge of the main content.

padding - pixels (24)
Width of the area between the floatbox content and the outer floatbox edges.

panelPadding - pixels (8)
Gap above and below the contents of the floatbox frame area like the caption and close buttons. Provides the vertical spacing between the floatbox outer edge, frame content, and main content.

overlayOpacity - 0-1 (0.55)
Opacity or darkness of the full-screen page overlay. 0 is fully transparent, 1 is fully opaque.

controlsOpacity - 0-1 (0.6)
Sets the opacity of the controls that can overlay the floatbox content area: the overlayed prev/next controls, the image resize widget at the top left, and the drag-resizer at the bottom right.

doAnimations - true | false
Setting doAnimations to false is a short-hand way of setting transitionTime, resizeTime and overlayFadeTime all to 0. When doAnimations is false, startAt, endAt, zoomSource, imageTransition and splitResize become irrelevant.

mobileDoAnimations - true | false
At its default setting of false, mobileDoAnimations turns off animations for mobile devices while letting desktop browser animatations be controlled by doAnimations. Note that if doAnimations is false, mobile animations won't occur regardless of the mobileDoAnimations setting. A mobile browser is defined as one that supports touch events and either has a small-format screen or does not have scrollbars.

overlayFadeTime - seconds (0.4)
Number of seconds for the opacity fade-in and fade-out of the translucent overlay which covers the host page.

resizeTime - seconds (0.5)
Controls the speed of the animated opening and closing resize of the floatbox from and to the thumbnail or click starting position.

fadeTime - seconds (0.4)
This is the time taken to fade in the box contents immediately after starting up the floatbox or before closing it down. If not overridden, tooltips will use 0.2 seconds for fadeIn and context boxes will use 0.

imageTransition - 'crossfade' | 'slide' | 'shift' | 'fade' | 'none'
A variety of animations are available when transitioning between two images in a gallery set. These transitions will be synchronized with any floatbox resizing that needs to occur such that all animations will complete simultaneously. The default transition setting is 'crossfade', which fades out the old image while fading in the new one and resizing the floatbox. An imageTransition setting of 'slide' does not alter opacity but instead will slide the current image out of the floatbox and thereby reveal a stationary next image underneath it. The 'slide' animation works particularly well in conjunction with touch or mouse swipes on the floatbox content to show the next (or previous) image. The 'shift' setting is similar to 'slide' except that instead of being stationary, the new image will slide into the box while the current image slides out, as if the two images were attached at their edges. A setting of 'fade' will cause the images to fade to black (or whatever the current colorTheme is), resize the box if necessary, and then fade the new image in from black. All transition animations can be turned off by setting imageTransition to 'none', in which case the new images will appear instantly without any transition effects.

transitionTime - seconds (0.6)
Controls the speed at which transitions between gallery set images occur.

showStartGif - true | false
Set this to false to hide the spinning gif that's shown during an animated box start or end, or when the fetch of the floatbox content over the network is taking a long time.

startAt - id | null
The default starting point for opening box animations is either at the click or touch location or from a thumbnail if the 'zoom' effect is being used. Set startAt to an id of an element on the page to start the animations from the center of that element. Set startAt to null to make the starting point the center of the screen.

endAt - 'start' | id | null
The endAt option controls the ending point that a floatbox will collapse to when animating out. If zooming from an image down to a thumbnail, the default closing point will be the thumbnail that matches the currently showing image. If not zooming to a thumbnail, the default closing location is at the mouse click or touch that opened the box. If neither of the above, it will go to the center of the screen.
Set endAt to an element's id to set the closing point to the center of that element. This could be useful for example when closing a shopping cart form and wanting to draw attention towards an updated cart link on the page. Set endAt to null to close to the center of the screen, and set it to 'start' to have it close to wherever it started from (which is usually the default behaviour anyway).

zoomSource - img filePath | null
Default behaviour for images is to do 'zoom' animations up from and down to the clicked anchor when opening and closing. The image zoomed is the same image that is being shown. The zoomSource option can be used to assign an alternate image to use for the zoom animation. Set zoomSource to the path of an image file to be used in the animation.
Any content type can have a zoomSource image assigned to it, so you can, for example, open a form by zooming up a screen capture image of that form. To disable the image zooming effect, set zoomSource to null.

zoomBorder - pixels (1)
Sets the border width around the zoomSource image for zooming in and out. Default is 1px.

splitResize - true | false
Default animated resizing of floatbox resizes width, height, top and left simultaneously. Setting splitResize to true yeilds sequenced animation where the X and Y dimensions are resized seperately. When split-resizing, the smallest dimension will be sized first, followed by the other larger dimension. This avoids unaesthetic resize behaviour of initially bloating up in the larger dimension. Note that splitResize does not take effect while 'zooming' an image in or out or while cross-fading between images in a gallery set.

colorTheme - 'black' | 'white' | 'blue' | 'silver' | 'yellow' | 'red' | 'custom'
When the colorTheme option is not specified, floatbox defaults to black for images, white for HTML content, and blue for multi-media. Assigning a specific colorTheme setting overrides these defaults. To use the 'custom' color theme, you must explicitly load the custom.css file in an include line on your pages immediately below the line for floatbox.css. The custom.css file can be modified to your preferences (hence the name).

boxColor - css color [|css color]
'boxColor' assigns the main background color of the floatbox's frame area using any css color. A gradient effect can also be assigned to the floatbox by setting boxColor to two css colors separated the the '|' character.
If defining a gradient, hex color formats must be used. For example: boxColor:#123456|#edca98
If a gradient is set, boxRoundCorners will be disabled and the floatbox will have square corners. Note that setting boxBackgroundImage can override a boxColor assignment.

overlayColor, innerBorderColor, outerBorderColor - css color
Assign any standard css color to various floatbox components using these options. The best approach when doing extensive appearance customizations is to set the desired options in a class definition in fbClassOptions on a page or in the global classOptions section of options.js. Once this is done, the collection of option settings can be assigned to one or more floatboxed links simply by placing the assigned class name on them.

textColor, strongTextColor - css color
These work the same as the other color options. 'textColor' applies to the 'item x of y' display, index links, and the 'open in a new window' link. 'strongTextColor' applies to captions, info and print links, and the new window link when it's hovered.

boxBackgroundImage - img filePath
The main floatbox frame area can have a background image assigned to it to give texture or other effects. Set boxBackgroundImage to the URL path of the image to be used as the background. Note that when this is set, boxRoundCorners is forced off and the floatbox will be displayed with square corners.

contentBackgroundColor - css color
The default background color of floatbox's content area is white for non-iframe HTML content and transparent for all others. If a different background color is required for some content, the desired color can be assigned by setting the 'contentBackgroundColor' option. Valid values are any color values that can be assigned via css. This setting will have a visible effect ony if the content shown has some transparent areas.

autoFit - true | false
Default behaviour for content that is larger than the viewable screen is to auto-size the floatbox such that it fits within the screen. Set autoFit to false to disable this auto-sizing. Note that auto-sizing never occurs for HTML content where the contentScroll option is set to false.

autoFitSpace - pixels (5)
The minimum space to leave between the floatbox edge and the browser window edge when autoFitting content.

measureHTML - true | false
The measureHTML option controls the measuring of HTML content and the automatic setting of a floatbox's height to match that measurement. The default behaviour when measureHTML is not set is to measure only if an explicit height option has not been assigned to the floatbox's opener. Set measureHTML to true or false to override the default behaviour.

enableImageResize - true | false
If enableImageResize is set to true, images that have been autoSized to fit the screen, that have been resized with drag-resizing, or are displayed larger than the current screen size can be resized using the resize tool.

inFrameResize - true | false
An image may be displayed at smaller than its native size when autoFit causes it to scale to fit the viewport. The image can then be resized to its full size using the resizeTool as described below. The default resizing behaviour is for the floatbox frame to remain at its smaller size inside the viewport and for the image to scale up to its full size inside the floatbox frame. It can then be dragged around inside the frame with the mouse or touch gestures. Set inFrameResize to false to disable this behaviour and to cause the entire floatbox, including the frame, to to scale up to full size when requested.

resizeTool - 'cursor' | 'topleft' | 'both'
Sets the tool used when enableImageResize is true. The cursor tool enables clicking on the image to resize and displays a magnifying glass to show when resizing is allowed. The topleft tool is a small semi-transparent button in the top left corner of the image.

enableDragResize - true | false
If true, a small resize widget will be shown in the bottom right corner that people can drag with the mouse to resize the box. Drag-resizing is always disabled on mobile touch devices because they have a better way of accomplishing the same task.

stickyDragResize - true | false
As with stickyDragMove, stickyDragResize instructs floatbox to remember dragged size changes between different items in a gallery. The stickyDragResize option applies only to proportionally resized content (images and multi-media) and has no effect on html content.

draggerLocation - 'frame' | 'content'
The widget that is shown when enableDragResize is enabled can be placed either in the bottom right corner of the floatbox frame or the bottom right corner of the displayed content by setting this option. (draggerLocation is always 'frame' for media content.)

minContentWidth (140), minContentHeight (100) - pixels
minContentWidth and minContentHeight set the lower limits for the dimensions a floatbox can be displayed at. A floatbox will be displayed at at least these dimensions and cannot be drag-resized or auto-sized smaller than these limits. These two options prevent content from becoming too tiny and may result in auto-sized floatboxes that are bigger than the viewport on zoomed small screens. minContentWidth and minContentHeight apply only to images and video and do not apply to HTML content, tooltips or context boxes.

maxContentWidth (0), maxContentHeight (0) - pixels
maxContentWidth and maxContentHeight set the upper size limits for floatbox content dimensions. When set to 0, no limit is in effect and the content will be presented at its native, specified or measured size.
If these options are applied to image content and are smaller than the image's native dimensions, the image will be resize-able up to native dimensions (provided the enableImageResize option has not been set to false).

minBoxWidth (0), minBoxHeight (0) - pixels | 'xx%' | 'max'
minBoxWidth and minBoxHeight can be used to setup a floatbox frame area larger than it would normally be based on the padding option and content size. In a gallery set or slideshow, this could be used to set up a box that fills the screen and remains a constant size while the content area inside the box changes to accommodate the various gallery set members.

boxLeft, boxTop - pixels | 'click' | '[-]xx%'
Default box positioning is for thefloatbox to open centered in the viewable browser screen area (with a little offset toward the top). The 'boxLeft' and 'boxTop' options can be used to change this default box placement. If set to simple integers, those integers will be taken as screen pixel locations at which to place the floatbox. These pixel placement values are relative to the visible browser viewport and not to the underlying document. If set to the string 'click', the floatbox's left and/or top edge will open at the mouse click or touch gesture location. 'boxLeft' and 'boxTop' can also be set to percentage values such as '-50%'. This will cause the floatbox frame to shift position that portion of the available free space. For example, a 'boxLeft' setting of '-50%' will move the floatbox half way to the left edge of the browser window.
Note that regardless of explicit positioning, a floatbox will reposition itself if necessary to appear within the visible viewport area because there is not much point in displaying content off-screen.

boxLeftAdjust, boxTopAdjust - pixels (0)
A floatbox can be dislocated from its natural position on the screen by setting boxLeftAdjust and boxTopAdjust to the pixel amounts of the dislocation. These options apply to tooltips and context boxes as well as standard floatboxes and can be useful for modifying the opening position of those components. As with boxLeft and boxTop, these option will not move content off-screen.

captionPos ('bl'), caption2Pos ('tc'), infoLinkPos ('bl'), printLinkPos ('bl'), newWindowLinkPos ('tr'), itemNumberPos ('bl'), indexPos ('br') - 'tl' | 'tc' | 'tr' | 'bl' | 'bc' | 'br'
These options control the positioning of the various widgets that can appear in the floatbox border area. See the 'layout' section of the instructions for more detail if required. Values are short-hand for top-left, top-center, top-right, bottom-left, bottom-center and bottom-right.

controlsPos - 'tl' | 'tr' | 'bl' | 'br'
Sets the positioning of the control panel in the floatbox frame. The control panel is the grouping containing control widgets like the close button, <<prev||next>>, etc. Values are short-hand for top-left, top-right, bottom-left and bottom-right.

outerClosePos - 'tl' | 'tr'
The round outerClose button can be shown either in the top-left or the top-right corner by setting outerClosePos to the desired value.

centerNav - true | false
The controls are positioned in one of the box's corners. Usually the < prev || next > controls are right beside the close button. With this option you can move the nav controls to the center of the top or bottom border area, away from the close button.

enableDragMove - true | false
If true, a floatbox can be dragged around the screen by holding down the left mouse button on the floatbox frame outside of the main content area, or on a displayed image (but not html or video content). On mobile touch devices, drag-moving works with a single-finger move gesture. If enableSwipeNav is set to true (its default) touch swipes on image content will not move the floatbox. For non-modal floatboxes (where the modal option is set to false) drag-moving is always enabled regardless of the value set for enableDragMove.

showMoveCursor - true | false
When enableDragMove is true (its default), setting showMoveCursor to true will cause the mouse move cursor to show whenever the mouse is hovered over a part of the floatbox by which it can be dragged around.

stickyDragMove - true | false
In sets of multiple floatbox items (galleries), if strickyDragMove is false the dragged location is not retained when navigating to the next item. Floatbox will return to its centered position with each new item. Set stickyDragMove to true to have floatbox remember its new screen position across item change-overs.

showClose - true | false
Enables/disables display of the close button in the floatbox border area.

showOuterClose - true | false
Enables/disables display of the round external close button that can be shown at one of the top corners of a floatbox.

showPrint - true | false
If showPrint is set to true, a "Print..." link will be shown in the floatbox border area. This print link invokes a print dialog that will print just the floatbox contents, not the underlying page. (The "Print..." text is translated/regionalized in the language files.) See the printCSS option for how to pass css stylings to the print content. Print links will not be shown for cross-domain iframe content because cross-domain script blocking will prevent the printing from succeeding.

printCSS - css text | css filePath
When showPrint is enabled, you may need to provide some css to format the print content the way you like. You can provide css settings directly as text. For example, printCSS:`h4 {color: #123456;} a img {border: 2px solid black;}`. Or you can set printCSS to the path of an external css file and this will be applied to the print window contents. E.g., printCSS:myPrint.css.

printText - string
Replaces the default text "Print..." (or the translated equivalent) used for the print link with text of your choice.

infoOptions - option string
Used in conjunction with the 'info' option, this allows assigning configuration options to the secondary info floatbox using the standard options attribute syntax. Wrap the infoOptions in backquotes for correct parsing and see the instructions and demo for more details.

infoText - string
Replaces the default text "Info..." (or the translated equivalent) used for the info link with text of your choice. For example, if you're displaying EXIF information through the info option, you may want to set infoText to "EXIF..."

showNewWindow - true | false
If showNewWindow is set to true, a "Open in a new window" link will be shown in the floatbox border area. Clicking this link will open a new browser window or tab with the floatbox content loaded as an ordinary page. ("Open in a new window" is translated/regionalized in the language files.) Use the showNewWindowIcon and closeOnNewWindow options in conjunction with showNewWindow.

showNewWindowIcon - true | false
This works in conjunction with the showNewWindow option. Set showNewWindowIcon to false to disable display of the small icon beside the 'Open in new window' text. (showNewWindowIcon is always false on rtl (right-to-left) layout pages.)

closeOnNewWindow - true | false
When set to true, floatbox will end (close) when the newWindow link (described in the options reference and instructions) is clicked.

controlsType - 'international' | 'english'
controlsType is closely related to the language option. Default when controlsType is not set is for visitors with localized English language browsers and large screens to see the floatbox control graphics that contain English text such as "close" and "next" while non-English or small-screen (e.g., smart-phone) browser users will see graphics-only controls without the English text on them. All browsers can be set to see the graphics-only controls by setting controlsType to 'international', or force English controls by setting this to 'english'.

strongControls - true | false
Setting this to true makes the controls (close button, prev/next, etc) appear always in their on or hovered state. This can be helpful when trying to match against a custom color that is set in the 'boxColor' option or in the css.

showHints - 'once' | true | false
Controls display of system tooltip messages on mouseover of the nav and control buttons. These tooltip messages are intended to be used to inform users about keyboard navigation shortcuts. With the default setting of 'once', each tooltip will deactivate after it has been displayed for sufficient time to be read. A tooltip message will also be deactivated if the user navigates with the associated keyboard shortcut. If enableKeyboardNav is set to false, showHints will be set to false.

outsideClickCloses - true | false
Default behaviour when outsideClickCloses is not set is for modal boxes, tooltips and context boxes to close when something outside the floatbox is clicked or touched. Set this to true to make non-modal boxes close on an outside click, or false to make any box ignore outside clicks.

contentClickCloses - true | false
If set to true, floatbox will exit when the user clicks on the floatbox's displayed content. This option is primarily useful for images and context boxes. By default, a context box will close when the page outside of the floatbox is click or touched, but remains open if interaction occurs within it's content. When set for images that have the navigation overlay active (navType = 'overlay' or 'both'), the click-to-close area is down the center of the image in the space remaining between the left and right navigation areas.

enableKeyboardNav - true | false
Enables or disables the keyboard handler for previous/next, pause/play, resize and close actions.

enableSwipeNav - true | false
Enables or disables use of a touch swipe gesture to navigate to previous or next images in a gallery set. This works especially well with 'imageTransition' set to 'slide'.

navType - 'overlay' | 'button' | 'both' | 'none'
Sets the type of navigation controls to display. 'overlay' is the "Prev/Next" image overlay.' 'button' gives "<<prev||next>>" in the controls area of the floatbox frame. Overlay navigation is not available for html and multi-media content, just for images.

navOverlayWidth - 0-50 (30)
Sets the width in percentage of each of the left and right transparent overlay nav panels that provide navigation through mouse clicks on the displayed image. If set to 50, each panel will be half the image width and so will meet without a gap in the middle. 40 leaves a 20% gap between panels, etc. If enableImageResize or contentClickCloses are active, you'll want to leave a gap between the nav panels so that there's somewhere on the image that can be clicked.

navOverlayPos - 0-100 (30)
When the mouse is active over an image with navType 'overlay' or 'both' set, small prev/next graphics are displayed. This setting is the percentage height from the image top that these graphics will appear. 0 puts them right at the top, and 100 places them at the bottom of the image.

showNavOverlay - 'once' | true | false
Controls display of the overlayed navigation 'prev' and 'next' graphics for image content. The default showNavOverlay is not set is to show the overlayed graphics only if the the button-style prev/next controls in the frame area are not present. If set to 'once', these graphics will be displayed only for the first image shown, and are turned off for other images once they have been seen.. When the overlay nav graphics are turned off overlay nav still works, it is just not displayed. When both the overlay and button nav types are enabled, the button nav controls will highlight as the mouse moves over active image areas. Use the 'navType' option to control whether the overlay and button navigation widgets are present or not.

showItemNumber - true | false
Setting showItemNumber to false will disable the display of the 'image/page x of y' text in gallery sets.

enableWrap - true | false
Enables gallery wrapping so that selecting 'next' on the last item wraps to the first, and selecting 'prev' on the first item wraps to the last. Because gallery viewing can start anywhere in a series of images, it is probably a good idea to leave this set to true in most circumstances. But if you are displaying something like a series of instructions that always starts with item #1 you may want to turn wrapping off. The enableWrap option affects only mouse and keyboard navigation. Even when enableWrap is set to false, a slideshow will wrap if started with an item other than #1 or if the afterSlideshow option is set to 'loop'.

numIndexLinks - number (0)
Index links are a grouping of numbered links that will jump floatbox to the selected item of a gallery set when clicked. They look like this: "1 2 3 4 5 ..."
If set to 0, no index links will be shown. If set to -1 or to a number greater than the number of items in a gallery set, all index links will be shown - one for each item in the gallery. If set to a positive integer less than the number of gallery items, only that number of links will be shown. For example, if maxIndexLinks = 9 for a 99 item gallery you get something like "1 ... 12 13 14 15 16 17 18 ... 99"

showIndexThumbs - true | false
Controls the display of popup thumbnails in the indexLinks group. If true, thumbnail popups will be displayed when an index link is hovered.

pipIndexThumbs - true | false
The default of true causes the popup thumbnails on index links to appear over-top of the content image in the corner closest to the index thumbs. If set to false, the thumbnails will appear immediately above or below the clickable index link numbers.

maxIndexThumbSize - pixels (0)
The popup thumbnails used in the index links are taken from the img elements inside the associated anchor on your base page. These thumbnails may be larger than you would like to see for the index links popup thumbnails. You can limit the popup size by setting maxIndexThumbSize to the pixel size you want the thumbnail's largest dimension restricted to. If maxIndexThumbSize is 0, the index link thumbnails will be shown at their native size.

indexThumbSource - img filePath | 'href'
When showIndexThumbs is true, the default index thumb source is the thumbnail image from a gallery item's associated anchor (link) element on the main page. If there is no such thumbnail, or if an alternate thumbnail is desired, the path to the desired thumbnail image can be specified in the indexThumbSource option. If indexThumbSource is assigned the value 'href', the main image linked to by the host anchor's href attribute will be used as the index thumb. When using the 'href' setting, you'll almost always want to set maxIndexThumbSize as well.

randomOrder - true | false
Gallery sets of multiple items normally are ordered by their position in the html document. By setting randomOrder to true, you can shuffle your gallery sets to a random order. This can be a nice touch for some slideshows.

doSlideshow - true | false
If set to true, images in a gallery set will be launched as a slideshow.

slideInterval - seconds (4.5)
This is the number of seconds to display each image in a slideshow before moving on to the next one. Per-item intervals can be assigned to the item options of individual slideshow members.

afterSlideshow - 'exit' | 'stop' | 'loop'
Describes what to do when all images in a slideshow have been seen. Note that if a slideshow was started on other than the 1st image, it will wrap around until all images have been seen before acting on the afterSlideshow directive.

showPlayPause - true | false
Turns display of the slideshow play & pause controls on or off.

startPaused - true | false
If true, a slideshow will start in a paused state. If false, the slideshow will auto-play on start.

source - a content reference
Every tooltip and context box requires a 'source' reference to be defined either in data-fb-tooltip or data-fb-context. This is the reference to the content that will be shown in the tooltip or context box. Commonly, source will point to a hidden div on the page with a syntax like "source:#myDivId", but it can also be a path to any type of floatbox content. e.g., "source:`myContent.html`" to bring in an external page as the tooltip or context box content.

placement - 'bottom' | 'top' | 'left' | 'right' | 'center'
The placement option determines where an enhanced tooltip will open in relation to the hovered element or the mouse location. If attachToHost is set to true, the tooltip placement is relative to the host element, otherwise it is relative to the location of the mouse cursor at the time the tooltip is invoked. If the requested placement would make the tooltip appear partially offscreen, the placement will be moved so that the entire tooltip shows.

attachToHost - true | false
Applies only to tooltips and, if true, will place the tooltip immediately adjacent to the host element (either above or below) and will not move with the mouse. This allows the mouse to be active inside the open tooltip and thereby allows clickable links to be placed in the tooltip content. (A tooltip can be assigned to an <area> element, but cannot be attached to it.)

moveWithMouse - true | false
Not surprisingly, if this is set to true for a tooltip, it will move with mouse movements. The default of false leaves the tooltip positioned at its starting location regardless of subsequent mouse moves.

showOnce - true | false
If showOnce is set to true, a tooltip will be displayed only on the first mouse-over of the host element per browser session. A session cookie will be set in the visitor's browser that will prevent the tooltip from re-appearing for that user until a subsequent visit.

delay - milliseconds (80)
Minimum delay in milliseconds between the element mouseover event and the display of the tooltip.

mouseSpeed - pixels per second (120)
The mouse must be moving at a speed less than mouseSpeed in order for the tooltip to appear.

fadeDuration - 0-10 (3)
This is a unitless setting (not seconds) that controls the duration of the opacity fade in and out of the tooltip when it starts and ends. 0 is no fade and 10 is very slow. Note fadeDuration is always 0 for Internet Explorer pre version 9 because IE is atrociously bad at fading text and tooltips usually contain text.

contextMouseButton - 'both' | 'left' | 'right'
This option applies only to context boxes and sets which mouse buttons will be used to trigger the display of the context box. Mobile devices will always respond to touch gestures regardless of the contextMouseButton setting. Please see the note in the 'Context boxes' section of the instructions for information about the unreliability of right-clicks in some browsers.

cycleInterval - seconds (5)
The number of seconds between each turnover of the displayed image in a set of cycling images or thumbnails. cycleInterval can be set on individual cycle set members to provide a different delay for different items in the set. See the 'Cycling images and thumbnails' section of the instructions for details.

cycleFadeTime - seconds (1)
Controls the speed of the fade in/out of the images in a set of cycling images or thumbnails.

cycleEnableClick - true | false
If set to true, a cycling image or thumbnail set can be paused and resumed by clicking or touching an image.

cycleShowControls - true | false
When cycleEnableClick is true, a visible play/pause control will be shown on a cycler set unless cycleShowControls has been set to false.

cycleControlsPos - 'tl' | 'tc' | 'tr' | 'bl' | 'bc' | 'br'
Controls the position of a cycler's visible play/pause control when cycleEnableClick and cycleShowControls are active.

cycleStartPaused - true | false
If set to true, a cycler set will begin in the paused state at page load. You'll want to set either cycleEnableClick or cycleResumeOnHover if starting paused.

cyclePauseOnHover - true | false
If set to true, image and thumbnail cyclers will pause and hold the current image while the mouse is hovered over the images. This option is ignored on mouse-less Mobile devices where the cyclers will always cycle.

cycleResumeOnHover - true | false
If set to true, image and thumbnail cyclers will start in a paused state and cycle only while the mouse is hovered over the images. This option is ignored on mouse-less Mobile devices where the cyclers will always cycle.

addVideoThumb - width | 'small' | 'medium' | 'large'
Floatbox can fetch video thumbnails from YouTube and Vimeo and can auto-insert these thumbnails into floatboxed anchors that reference videos from these services. The fetched thumbnail will be displayed at the size specified in the addVideoThumb option which can be an explicit pixel width, 120px for 'small', 480px for 'large', and a default of 240px for 'medium' or other non-numeric value (such as true). Setting addVideoThumb on any anchor other than one that references a video from somewhere other than youtube or vimeo will have no effect.

addPlayButton - 'small' | 'medium' | 'large'
Any floatboxed anchor that contains a thumbnail can have a translucent play button displayed over top of it by setting the addPlayButton option to the desired button size (small, medium or large). The default action is to add a medium-sized play button to thumbnails added by the addVideoThumb option and to do nothing with other thumbnails. Use the addPlayButton to show a button on standard thumbnails or to change the button size for addVideoThumb thumbnails. Note that the 'small', 'medium' and 'large' settings set a size relative to the host thumbnail, and not an absolute pixel size.

fetchVideoInfo - true | false
When videos from YouTube or Vimeo are configured to show in a floatbox, the API services of those providers will be queried to fetch useful information about the video such as the title and default size. (YouTube unfortunately does not provide size info.) If you prefer to not incur the network overhead of these API queries and instead provide explicit size and caption info for your videos, set fetchVideoInfo to false. This can be set per-item in data-fb-options and per-page or globally.

titleAsCaption - true | false | 'a' | 'img'
If a caption is not assigned directly with the caption option, titleAsCaption, when left at its default value of true, will pull a caption in from a title attribute found on the host anchor or on a thumbnail img element within that anchor. A setting of 'a' instructs it to look at title attributes only on the anchor element and a setting of 'img' causes it to look for titles only on thumbnail img elements. To disable the setting of captions from title attributes, set titleAsCaption to false. See the 'caption' and 'caption2' options for details on how to set caption content directly. The titleAsCaption option also applies to fbCycler sets and will cause the cycler captions shown below the images to be pulled from the img elements' title attributes.

altAsCaption - true | false
If altAsCaption is set to true and a caption has not been assigned either through the caption option or as a result of the titleAsCaption option, the caption will be pulled from the alt attribute on a thumbnail image inside the floatboxed anchor. The altAsCaption option also applies to fbCycler sets and will cause the cycler captions shown below the images to be pulled from the img elements' alt attributes.

hideObjects - true | false
If true, objects and embeds (flash, quicktime, silverlight, etc.) on the host page will be hidden while a floatbox is being displayed. This is generally a good idea as most objects will appear on top of the floatbox display if not hidden. Flash objects using the default wmode of 'window' have this problem (feature?). If you set your flash objects to have a wmode of 'opaque' or 'transparent' they will not appear over top of the other content and you won't need to enable hideObjects.

hideJava - true | false
Just like hideObjects but for Java applets.

showMagCursor - 'once' | true | false
Changes the mouse cursor to a small magnifying glass when the mouse is hovered over a thumbnail in a floatboxed anchor. If set to 'once', the cursor will change only for the first mouseover on the thumbnail image. Note, that some browsers cannot and will not show the custom cursor regardless of this option's setting. (Older Opera, most Mac browsers except Safari, and some Linux browsers are guilty of this.)

modal - true | false
When modal is true, floatbox will overlay the whole page with a translucent layer, the underlying page will be unreachable until the box is closed, and any secondary floatboxes will be stacked on top of any already-opened boxes. Setting modal to false removes the translucent page overlay, allows the underlying page to be accessed while one or more floatboxes are open, and allows multiple open floatboxes to be re-arranged and restacked.

centerOnResize - true | false
When set to true, all open floatboxes will reposition themselves towards the center of the screen when the browser window is resized, and will resize to fit the new window dimensions if autoFit behaviour is enabled.

boxScroll - true | false
If boxScroll is set to false, floatbox will use fixed positioning. Fixed positioning locks the floatbox in a fixed screen location that will not move in response to scrollbar actions. Because scrolling is not available when fixed positioning is used, boxScroll is ignored if the current displayed content is larger than the available screen dimensions. Note that some browsers (IE 6 and a bunch of mobile devices) cannot do fixed positioning and boxScroll will have no effect on these platforms.

pageScroll - true | false
When fixed positioning has been assigned by the boxScroll:false option, the scrollbars on the main page can be removed by setting pageScroll to false. This will prevent scrolling of the host page underneath the floatbox when the mouse wheel is used to scroll content inside a fixed-position floatbox.

minFlashVersion - version string ('9.0.115')
When direct-loading flash, you can require that a minimum version of flash is installed on the visitor's browser. If the required version is not present, floatbox will show a language-localized message to that effect and present a link for getting the latest flash version. The version string must include the major version number and may include the minor and revision numbers. For example, 10, 10.1 and '10.1.23' are all valid version strings. The default is version 9.0.115 because this is the oldest Flash player that can handle mp4 video content.

autoEndVideo - true | false
A floatbox showing video either with the built-in HTML5 video player or from YouTube or Vimeo will close automatically when the video ends unless autoEndVideo is set to false. (Doesn't always work in IE pre version 9.)

mobileNewWindow - true | false
When set to true, devices with small screens (generally, mobile phones) will open the target content in a new browser window while larger-screened browsers will open the content in a floatbox. This is useful when the content to be displayed is too large to handle cleanly on the small device screens. Default behaviour is to show all cross-domain iframes and direct-loaded pdf content in a new window on small-screen devices. Set mobileNewWindow to false to force content to always show within a floatbox regardless of screen size.

instanceName - string
instanceName is used in conjunction with the API function fb.getInstance to programmatically reference a particular floatbox when more than one is present. If no instanceName is provided, the default instance name will be the filename of the opening content. For example, if you show "/images/my_toys.jpg" in a floatbox, and don't assign a specific instanceName, the box's name will be "my_toys". See the API Reference for fb.getInstance() details.

attachTo - 'click' | elementID
Use 'attachTo' to enhance accessibility of web pages by providing correct sequencing or placement of floatbox content in the HTML DOM hierarchy, or to attach the floatbox to an ASP.NET form. When set to 'click', the floatbox will attach in the document tree just after the element that was clicked to launch the floatbox. To place the floatbox inside a particular element, such as a form, specify the id for that element. More information is available in the 'Attach to a specific document element' section of the instructions.

zIndex - number (77777)
Floatbox's default z-indices begin at 77777. If there is other content on a page that is set higher than this (such as maybe a navigation menu), a larger zIndex can be assigned to the floatboxes by setting this option. If you are having trouble with flash objects appearing above the floatbox regardless of zIndex, please see the 'hideObjects' option.

framed - true | false
Use the framed option to attach floatbox to an iframe or frameset child window. This will constrain floatbox to the frame area only instead of having it overlay the entire top document. For frameset pages, floatbox.js must be included in a child frame document, not in the frameset document itself, and the 'framed' option must be set. The 'framed' option can be set either as a querystring on the floatbox.js include line, or set to true in fbPageOptions that is defined prior to loading floatbox.js. See the "Constraining Floatbox..." section in the instructions for details and examples.

preloadLimit ** - 'x|y' ('5|1')
Floatbox will preload images that are referenced by floatboxed anchors so that those images may be shown immediately when clicked instead of the visitor possibly watching the spinning loader graphic while waiting for the image to be fetched across the network. (Preloading starts shortly after the main page is fully rendered and window.onload fires). preloadLimit sets the number of referenced images that will be preloaded. Two values can be provided, separated by a '|' character, with the left-side value applying to non-touch devices and the right-side value applying to devices that support touch gestures. If just a single number is provided, it will apply to all devices.

language ** - 'en' | ... (see the languages folder)
Floatbox provides international localization through the json files in the languages folder. When the language option is not set, floatbox will detect the visitor's browser language preference and use that language for its system tooltips and other text. You can force a particular language by assigning it here. Doing this will set that language for everyone visiting your site, regardless of where they are coming from.

activateOnClick ** - true | false
Setting activateOnClick to true will cause Floatbox's fb.activate() API function to run every time a mouse click or touch event occurs on the main document. This can be useful as an easy way to 'light up' floatboxed elements that have been dynamically added to a page some time after the page has loaded. Note that activateOnClick doesn't help when bringing in new fbTooltip elements because their mouseover behaviours won't be assigned until the user clicks something on the page. See the 'Dynamically loading Floatbox content via AJAX, script or UpdatePanel' section of the instructions for more details.

floatboxClass ** ('floatbox'), cyclerClass ** ('fbCycler'), tooltipClass ** ('fbTooltip'), contextClass ** ('fbContext') - className
The class names that are used to activate floatbox elements can be changed in order to avoid conflicts with other html and css. For example, if the 'floatbox' class is already used for other purposes, the floatboxClass option could be changed to 'floater' or any other unused class name.
The floatboxClass option can accept multiple class names by separating them with a '|' character (e.g., floatbox|foo|bar. This can be helpful when working with CMS platforms that allow assignment of only one class to any particular element.
