I did it on my site without a message board, I had to do some re-writes to make the login area go into a new directory that is protected with the iBill .htaccess file. So all users can see all thumbnails buy only registered users can see the full image. Then they register and confirm there email. Then when they try to login they need to have an iBill login name before they can log into the PhotoPost. Only draw back is the cookies, if there account expires and they still have the cookie on there system they do not need to login and since they don't have to login they have full access until there cookie expires. Guess thats a small price to pay to make a few bucks.
