requires prettyPhoto
prettyPhoto is a great jQuery lightbox. If you find that you need more than one link on the page to launch a gallery, prettyPhoto Launcher will do the trick.
Example:
<ul> <li><a href="fullsize/image01.jpg" rel="lightbox[gallery]"><img src="thumbnails/image01.jpg"/></a></li> <li><a href="fullsize/image02.jpg" rel="lightbox[gallery]"><img src="thumbnails/image02.jpg"/></a></li> <li><a href="fullsize/image03.jpg" rel="lightbox[gallery]"><img src="thumbnails/image03.jpg"/></a></li>
