With the current setup, the center box has fancybox behaviour attached to it.
Note the extra javascript in the header and the "fancy" class and optional galleryname on the link tags.
This example can probably be adapted to other lightboxes etc.
This last frame doesn't have fancybox attached to it. Clicking it will not do much.
