I changed images all to png still see nothing. Perhaps they are to large?
NO.

Doesn't RGUI support thumbnails?
It does actually, but I have a feeling that however Black-Seraph compiles the project that feature has been stripped? I could be wrong, but I can't seem to get it working.
I am going to move full sets to root dir ra for easier browsing in RA.
