Lightbox2 JS is a simple, unobtrusive script used to overlay images on the current page. It's a snap to setup and works on all modern browsers. The module comes with a Lightbox2 Lite option which does not use the JQuery libraries; it is therefore less likely to conflict with anything else.

Places images above your current page, not within. This frees you from the constraints of the layout, particularly column widths. Keeps users on the same page. Clicking to view an image and then having to click the back button to return to your site is bad for continuity (and no fun!).

Features

The version 2 module has several benefits over the plain Lightbox module. Note, not all of these features are available when the "Lightbox2 Lite" option is enabled.

• Image Sets: group related images and navigate through them with ease - ideal for your image galleries.
• Slideshow Capability: automatically transition between grouped images, includes play/pause and previous and next buttons.
• HTML Content Support: ability to show websites or other HTML content in a lightbox.
• Video Content Support: ability to show videos in a lightbox.
• Visual Effects: fancy pre-loader and transition when you click on the image.
• Keyboard Shortcuts: useful keyboard shortcuts for switching between images, toggling play / pause, etc.
• Zoom Capability: larger images are reduced in size so they fit snugly inside the browser window. A zoom button can then be clicked on to see it in its original size.
• Automatic Image Detection: configurable automatic re-formatting of image thumbnails, so there is no need to add 'rel="lightbox"' to each image link on your site. Image, Inline, Flickr, Image Assist and CCK Imagefield modules are all supported. It's also possible to configure a custom list of image classes which should trigger the lightbox functionality.
• Imagecache Support: adds a Lightbox2 field formatter for CCK imagefields for your custom views.
• Image Page Link: a link to the image node can be provided within the lightbox itself.
• Page Exclusion Capability: exclude certain pages on your site from having the lightbox2 functionality.
• Login Support: ability to modify all user/login links so the login form appears in a lightbox.
• Skin and Animation Configuration: configure the order and speed of the lightbox animations, along with the lightbox colors, border size and overlay opacity.
• Gallery 2 Support: support for Gallery 2 images via the Gallery module (beta).

Usage

Adding a Basic Lightbox

Add rel="lightbox" attribute to any link tag to activate the lightbox. For example:

Optional: To show a caption either use the title attribute or put in the second set of [] of the rel attribute.

Grouping Images

If you have a set of related images that you would like to group, follow step one but additionally include a group name between square brackets in the rel attribute. For example:

No limits to the number of image sets per page or how many images are allowed in each set.

If you have a set of images that you would like to group together in a lightbox, but only wish for one of these images to be visible on your page, you can assign the "lightbox_hide_image" class to hide the additional images. For example:

<a href="images/image-1.jpg" rel="lightbox[roadtrip]">image #1</a>
<a href="images/image-2.jpg" rel="lightbox[roadtrip]" class="lightbox_hide_image">image #2</a>
<a href="images/image-3.jpg" rel="lightbox[roadtrip][caption 3]" class="lightbox_hide_image">image #3</a>

Slideshow

This is very similar to the grouping functionality described above. The only difference is that "rel" attribute should be set to "lightshow" instead of "lightbox". Using the same example as above, we could launch the images in a slideshow by doing:

<a href="images/image-1.jpg" rel="lightshow[roadtrip]">image #1</a>
<a href="images/image-2.jpg" rel="lightshow[roadtrip][caption 2]">image #2</a>
<a href="images/image-3.jpg" rel="lightshow[roadtrip][caption 3]">image #3</a>

Video Content

It's possible to show video content in the lightbox. In this case the "rel" attribute should be set to lightvideo. It's possible to group videos and to control the size of the lightbox by setting the 'width' and 'height' properties. The properties can be configured like lightvideo[group|width:300px; height: 200px;] and lightvideo[|width:300px; height: 200px;][my caption]. The properties should all be of the format "property: value;" - note the closing semi-colon. If no properties are set, then the default width and height of 400px will be used. See below for more detailed examples.

Basic example:
<a href="http://video.google.com/videoplay?docid=1811233136844420765" rel="lightvideo">Google video example - default size</a>

Basic example with caption:
<a href="http://video.google.com/videoplay?docid=1811233136844420765" rel="lightvideo[][my caption]">Google video example - default size</a>

Grouped example:
<a href="http://video.google.com/videoplay?docid=29023498723974239479" rel="lightvideo[group][my caption]">Grouped example 1</a>
<a href="http://video.google.com/videoplay?docid=1811233136844420765" rel="lightvideo[group][my caption]">Grouped example 2</a>

Controlling lightbox size example:
<a href="http://video.google.com/videoplay?docid=1811233136844420765" rel="lightvideo[|width:400px; height:300px;][my caption]">Google video example - custom size</a>


Supported Video Formats:
asx, wmv, mov and swf videos should all be supported. A number of video providers are also supported, for example YouTube and Google Video. For full details on how to integrate these with lightbox, please see the online documentation.

HTML Content

It's possible to show webpage content in the lightbox, using iframes. In this case the "rel" attribute should be set to lightframe. Again it's possible to group the items, (e.g. lightframe[search]) but in addition to that, it's possible to control some of the iframe properties. It's possible to set the 'width', 'height' and 'scrolling' properties of the iframe. The properties are separated from the group name by a |, for example lightframe[search|width:100px;] and lightframe[search|width:120px][my caption]. If no grouping is being used, then the | is still used and the format would be lightframe[|width:100px;]. The properties should all be of the format "property: value;" - note the closing semi-colon. If no iframe properties are set, then the default width and height of 400px will be used. See below for more detailed examples.

Basic example:
<a href="http://www.google.com" rel="lightframe[][Search Google]">Search google</a>

Grouped example:
<a href="http://www.google.com" rel="lightframe[search]">Search google</a>
<a href="http://www.yahoo.com" rel="lightframe[search][Search Yahoo]">Search yahoo</a>

Controlling iframe property example:
<a href="http://www.google.com" rel="lightframe[|width:400px; height:300px; scrolling: auto;]">Search google</a>

Controlling iframe property when grouped example:
<a href="http://www.google.com" rel="lightframe[search|width:400px; height:300px; scrolling: auto;]">Search google</a>
<a href="http://www.yahoo.com" rel="lightframe[search|width:400px; height:300px;][Search Yahoo]">Search yahoo</a>

Inline Content Support

It's possible to show HTML snippets in the lightbox, that is on the same domain. In this case the "rel" attribute should be set to lightmodal. Again it's possible to group the content, (e.g. lightmodal[search]) but in addition to that, it's possible to control some of the inline / modal properties. It's possible to set the 'width', 'height' and 'scrolling' properties of the inline content. The properties are separated from the group name by a |, for example lightmodal[search|width:100px;] and lightmodal[search|width:100px;][my caption]. If no grouping is being used, then the | is still used and the format would be lightmodal[|width:100px;]. The properties should all be of the format "property: value;" - note the closing semi-colon. If no properties are set, then the default width and height of 400px will be used. See below for more detailed examples.

Basic example:
<a href="search.php" rel="lightmodal">Search</a>

Basic example with caption:
<a href="search.php" rel="lightmodal[][my caption]">Search</a>

Grouped example:
<a href="search.php" rel="lightmodal[search]">Search</a>
<a href="search.php?status=1" rel="lightmodal[search][published]">Search published content</a>

Controlling modal property example:
<a href="search.php" rel="lightmodal[|width:400px; height:300px; scrolling: auto;]">Search</a>

Controlling modal property when grouped example:
<a href="search.php" rel="lightmodal[search|width:400px; height:300px; scrolling: auto;]">Search</a>
<a href="search.php?status=1" rel="lightmodal[search|width:400px; height:300px;][Search published]">Search published content</a>
<a href="search.php?status=0" rel="lightmodal[search|width:400px; height:300px;][Search Unpublished]">Search unpublished content</a>

Keyboard Shortcuts

The default keyboard shortcuts are listed below. You can override these on the admin page.

Not all of the keyboard shortcuts work in the Opera browser, for example "z" for toggling the zoom and "spacebar" for toggling play / pause in slideshows. This can be overcome by updating your shortcut settings in the Opera preferences editor.
