mod to protect pictures

[carlo1]

is it possible to protect my pictures for everyone who is not registered. non registered people should only see the categories and the thumbs, but he can´t see the bigger one. i think that is possible and here is one mod but i have no idea for which name i must look here in the board. sorry for this.
also i hope i can make more groups (friends - this group can see all picture; non friends - this group can e.g. only see some categories)

please help me. i use 1.41

thank you

However, cpg1.4.x goes currently unsupported as you should be well aware of. Posting in feature requests isn't a good idea neither, as it's not the place where support requests should go at all.
