I have a question regarding the integration of FancyBox. I would create a gallery with 10 pictures but only one thumbnail. For example: http://fancyapps.com/fancybox/demo/ T
You can simply add display:none to the links you don't want to show.
e.g. http://jsfiddle.net/MvvuE/
You need a link to all the images in your gallery regardless they show a thumbnail or not so you may have this html
<a class="fancybox" rel="gallery" href="image01.jpg"><img src="thumbnail01.jpg" alt="" /></a>
<a class="fancybox" rel="gallery" href="image02.jpg"></a>
<a class="fancybox" rel="gallery" href="image03.jpg"></a>
<a class="fancybox" rel="gallery" href="image04.jpg"></a>
etc. ... in that way, only a single thumbnail is shown and the rest of the links are not visible but functional.
Then a script like this will fire the gallery
$("a.fancybox").fancybox();
