Added a image set with lightbox. I think all the paths are correct, but the thumbnails are showing! the lightbox itself works fine.
Any ideas?

I don't get what is your problem?? You don't want the thumbnails to be shown or what??
I can see all the pics that are listed inside the image set. If you don't want to show all of the thumbnails check out what I did with this gallery
