@Dmancini

Subalbums and mod_rewrite don't play well together right now. Tristan is in the development stages on this, but for now, if you want to use subalbums, you need to turn mod_rewrite off.

They work fine with mod_rewrite off though.

Ok, you mean I have to change this

RewriteEngine On

with

RewriteEngine Off

correct?

Everything looks to be messed up here

Nope, actually it's the parameter in zp-config.php in your /zen directory.

Change:

$conf['mod_rewrite'] = true;

to:

$conf['mod_rewrite'] = false;

The gallery is currently messed up because you turned off the actual rewriting, but Zenphoto still thinks the URLs should be mod_rewritten.
