Hi, I've got everything setup and configured the way I like it. ZP is great!

However, I noticed that a password protected album is not locked once it's been unlocked. I tried logging out a few times, but the album stays "open".

Can I set up a password protected album that will always be protected after a session ends or the browser is closed? Is there a lock link/button for those users (clients) doesn't know how to lock the album again?

Thanks!

You can use album sessions. Otherwise passwords are stored in cookies. You have to use the user logout plugin (and the current Zenphoto) to get a logout which will clear ALL login cookies.
