Adding "use must register/login to see..." when guest clicks on thumbnail (permissions)

Hi folks,

My current permission settings for new albums/users are:
Registered Users [core] View all versions
Registered Users [comment] Add comments
Registered Users [rating] Add ratings
Everybody [rating] All access
Everybody [core] View item
Everybody [comment] View comments
Site Admins All access

What's the setting so that a non-registered or non-logged in user will get a "you must register/login to view the picture"?...

It's set right now where anybody not logged in will just get a thumbnail when they click on a thumbnail. It would be nice to get the "you must log in or register..."
