how to set album permissions?

[burnhard_1979]

hey outta there ppl,

my page is http://feuerwehr.heldenfotos.at. Right now you have to be registered user to view the pics inside. That is ok but also I would like to have albums which can be viewed by everyone and also albums which can just be viewed by registered users.

I know I have to switch of this "you have to be registered user" permissions and I have to add the group I would like to permit to the albums but WHERE is this button to add a specific group in the album properties - I don't have such a button!!! :-(

may somebody please help me? thanks in advance, best regards, burnhard_1979
