Main page images invisible to Guests and unregistered

[PeterPan]

I run a bridged CPG 1.32 with phpbb 2.0.10, works perfectly fine. Set to No registrations allowed.
The problem is that after a while users find the direct link to the Gallery, and can freely see and click anywhere they like.

Question A :   how can I make it so that not logged in guests can't see any any pictures?

Question B :  or how can I hide the whole CPG from people not coming via my board? That would be best.

Thanks in advance.

Pic viewing permissions are covered in the documentation, and to restrict traffic maybe only make the link from the board visible to logged in users.
