I get this when ever I try to admin a sub album.

Forbidden
You don't have permission to access /zenphoto/zp-core/admin.php on this server.

Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.
Apache/1.3.41 Server at www.melbarr.ca Port 80

What did I do wrong this time...

Check the permissions on your folders.

It is set to 777, read/write/execute in all aspects temporarily and it still gives me the meassage....

Is that permission on the folder or on the file admin.php? (or both?) The error you are getting indicates that the WEB browser is not permitted to access/execute the admin.php file.

That is on the whole Zenphoto folder and all files/directories underneath...
