[SOLVED] View Full Size Problem

It seems that I cannot turn off the ability for registered users to view full size. I want no one to be able to view full size and I cannot seem to be able to get that to work. I have set the album permissions to denied for both everybody and registered but still the registered users can view full size images.

Any ideas?

Thanks,

John

Update: Reversed some edits made to play with fancybox now shadowbox is working again so really not needed. Thanks
