Fancybox for JQuery is useful for those little pop-up image galleries, but it only works on images within links that are grouped by having the same "rel" tag. If you want to use another tag, apply this patch (to 1.3.0).

You can then use the new "attributeType" to pass the tag type when calling the script.

Great idea for a new year's resolution.
