When I ran my test I ran through all the steps...
Made sure I was logged out and cleared all history and cookies etc...
As a Unregistered Guest I could view thumbnails (Of course when I clicked on them I got the correct message)
Then I registered as a member (great integration to my forums BTW) as a "Member" I should not be allowed to view anything and I couldn't so that works. All the thumbnails I saw as an unregiesterd guest were not visible when I registered....
....Does that make sense or did I confuse you
