deny access to images

[citra]

basically this is what i'm trying to do.

I have a category with bunch of pictures. some are just normal pictures while others might be considered 'adults only'.
so I want to create 2 usergroups to limit what they can and cannot see. first group 'normal' will only be able to see the normal pictures. but if a user is in the 'adults' group, they'll be able to see all of the pictures.

I can get this to work if I create 2 separate categories however I want to know if there's a way to do this within a single caterogy. Thanks!

There's not a way to do it without putting them in different categories.
