I am a newbie to zenphoto and I am trying to lock my albums, I have been able to apply the lock to the album but when you get into the album and try to click on a thumbnail you are then directed back to the login page. What am I doing wrong?

Do you mean password protect the album? It is possible that cookies are not working on your site or client computer. You can try setting the option for album sessions.

I tried checking the enable gallery sessions check box and I have the same problem. I password protect the album and when you put in the username and password it takes you to thumbnails but when you click on a thumbnail it prompts you to put in your login info again and when you do it brings up a blank page.
