Hello/Hi/Greetings,

Each Photo in a gallery has an option "Who can see this photo" with pre-defined groups Administrator/Friends/Family/Contacts/Everybody.
However, where do I define who belongs to these categories.
Cannot find anything under Configuration and I currently have no groups defined under Users/Groups.
I would like to add a user that I already created to one of these pre-defined groups.
Thanks
