Hi all,
I have an installation on my server which the public won't access. Is it possible to remove the login system altogether and just allow ayone who visits the site to upload photos? I don't need user permissions or anything, just for anyone to be able to upload photos.
Thank you.

Line 7 of zen/auth_zp.php, change:
$_zp_loggedin = false;
to:
$_zp_loggedin = true;
to make it default to being logged in. If you like you can even comment out all the login logic to save CPU cycles... the if/else block, lines 13 to 39.

Thank you very much.
