Permission has been granted to Mark Ashmead & other Drupal Lightbox2 module maintainers to distribute the original lightbox.js via Drupal.org under this license scheme. This file has been subsequently modified to make use of jQuery instead of prototype / script.acalo.us. This module enables the use of lightbox2 which places images above your current page, not within. This frees you from the constraints of the layout, particularly column widths. This module will include the lightbox CSS and JS files in your Drupal Installation without the need to edit the theme. 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. INSTALLATION ------------ 1. Copy lightbox2 folder to modules directory. 2. At admin/build/modules enable the lightbox2 module. 3. Enable permissions at admin/user/permissions. 4. Configure the module at admin/settings/lightbox2. 5. Modify your image links to open in a lightbox where necessary, see "Adding Lightbox Functionality to your Images' section below. ADDING LIGHTBOX FUNCTIONALITY TO YOUR IMAGES -------------------------------------------- No Grouping =========== Add rel="lightbox" attribute to any link tag to activate the lightbox. For example: image #1 image #1 Optional: To show a caption either use the title attribute or put in the second set of [] of the rel attribute. With Grouping ============== 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: image #1 image #2 image #3 No limits to the number of image sets per page or how many images are allowed in each set. Go nuts! 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: image #1 image #2 image #3 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: image #1 image #2 image #3 Video ===== It's possible to show video content in the lightbox. In this case the "rel" attribute should be set to "lightvideo". It's not possible to group videos but it is possible to control the size of the lightbox by setting the 'width' and 'height' properties. The properties can be configured like "lightvideo[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: Google video example - default size Basic example with caption: Google video example - default size Controlling lightbox size example: Google video example - custom size 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 Support ==================== 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 content, (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:100px;][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: Search google Basic example with caption: Search google Grouped example: Search google Search yahoo Controlling iframe property example: Search google Controlling iframe property when grouped example: Search google Search yahoo 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: Search Basic example with caption: Search Grouped example: Search Search published content Controlling modal property example: Search Controlling modal property when grouped example: Search Search published content Search unpublished content Turning the Image Caption into a Link ===================================== If you wish to turn the caption into a link, format your caption in the following way: image #1 Note, the < and > characters have been changed to their HTML entities, and the " have been escaped. KEYBOARD SHORTCUTS ------------------ 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. Close : x, o, c, ESC Previous Image : p, Left Arrow Next Image : n, Right Arrow Toggle Zoom : z (not available in slideshow) Toggle Play / Pause : Spacebar (slideshow only) KNOWN ISSUES ------------ Lightbox Lite in IE -------------------- There is an issue with Lightbox Lite in IE browsers but only for sites where Drupal is installed in a subdirectory. In such instances, the overlay.png image can not be found. To overcome this issue you will need to edit the lightbox2/css/lightbox_lite.css file and change the path to this image. By default the line is set to: filter: progid:DXImageTransform.Microsoft.AlphaImageLoader(src="../images/overlay.png", sizingMethod="scale"); You will need to change the image path on this line to be the full path, e.g. filter: progid:DXImageTransform.Microsoft.AlphaImageLoader(src="/sites/all/modules/lightbox2/images/overlay.png", sizingMethod="scale"); See http://drupal.org/node/185866 for more details. Keyboard Shortcuts in Opera --------------------------- 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.
