How to Use:

Part 1 - Setup

  1. Lightbox v2.0 uses the Prototype Framework and Scriptaculous Effects Library. You will need to include these four Javascript files in your header.
    <script type="text/javascript" src="js/prototype.js"></script>
    <script type="text/javascript" src="js/scriptaculous.js?load=effects"></script>
    <script type="text/javascript" src="js/Sound.js"></script>
    <script type="text/javascript" src="js/lightboxEx.js"></script>
  2. Include the Lightbox CSS file (or append your active stylesheet with the Lightbox styles).
    <link rel="stylesheet" href="css/lightboxEx.css" type="text/css" media="screen" />
  3. Check the CSS and make sure the referenced prev.gif and next.gif files are in the right location. Also, make sure the image files as referenced near the top of the lightboxEx.js file are in the right location. You would need to set homeURL variable pointing to your installation directory.

Part 2 - Activate

  1. Add a rel="lightbox" attribute to any link tag to activate the lightbox. For example:
    <a href="images/image-1.jpg" rel="lightbox" title="my caption">image #1</a>
    Optional: Use the title attribute if you want to show a caption.
  2. 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:
    <a href="images/image-1.jpg" rel="lightbox[roadtrip]">image #1</a>
    <a href="images/image-2.jpg" rel="lightbox[roadtrip]">image #2</a>
    <a href="images/image-3.jpg" rel="lightbox[roadtrip]">image #3</a>
    No limits to the number of image sets per page or how many images are allowed in each set. Go nuts!
  3. By default, sets images are displayed in slideshow mode. You can change any default parameters by going to configuration section in lightboxEx.js file. Make shure you set homeURL variable pointing to your installation directory.
  4. You can set the following parameters to customize your slideshow by adding them as attributes to the first link of your images from slideshow:
    startslideshow = true slideshow auto start. Set to false if you want to disable starting slideshow automaticaly.
    slideshowwidth = 604 set it to -1 to size slideshow window based on each image.
    slideshowheight = 454 set it to -1 to size slideshow window based on each image.
    navbarWidth = -1 set it to -1 to size navigation bar based on width of each image.
    slideDuration = 4 set image swap interval in seconds.
    loopMusic = true loops music if it is shorter then slideshow.
    forever = false Set false if want to stop on the last image or Set it to true for Infinite loop feature.
    music = "music/song.mp3" URL to your misic MP3 file.
    For example:
    <a href="http://www.huddletogether.com/projects/lightbox2/images/image-3.jpg" rel="lightbox[plants]" slideshowwidth=-1 slideshowheight=-1 music="music/song.mp3" ></a>



It doesn't work at all. The image opens up in a new page. What's wrong?
This is commonly caused by a conflict between JS scripts. Check your body tag and look for an onload attribute. Example:
<body onload="MM_preloadImages(‘/images/menu_on.gif’)…;">
A quick fix to this problem is to append the initLightbox() to the onload attribute as so:
<body onload="MM_preloadImages(‘/images/menu_on.gif’)…;initLightbox()">
Flash objects appear through overlay.

Script doesn't work with imagemaps.
Refer to comment by Jason Buechler.
The shadow overlay doesn't stretch to cover full browser window.
Remove the default margin and padding from the body tag. Add body{ margin: 0; padding: 0; } to your stylesheet.
Can I insert links in the caption?
Yes, but you need to convert quotes and greater and less than symbols into their html entity equivalents. For example:
<a href="images/image-4.jpg" rel="lightbox" title="&lt;a href=&quot;link.html&quot;&gt;my link&lt;/a&gt;">Image</a>
Can I display flash, video, or other content using the script?
Not out of the box, but if you're feeling brave, open up and modify the code to suit your needs. As an alternative, you can give Cody Lindley's ThickBox script a go.
Can I use the script in a commercial project?
Yes. It is licensed under the Creative Commons Attribution 2.5 License.
