Album Permissions

Hey Guys,

I'm hoping someone can help me accomplish what I'm trying to do here. I'm using the Classic layout which dsiplays my two albums and their list of sub albums on the main gallery page when i'm logged in. What I want to do is make these galleries and the list of subgalleries visible on the main page even if I'm not logged in. Then, when someone clicks on the album it will ask them to login. Can this be accomplished easilly?

Thanks
