Hi there! I'm working on a Facebook like Photo Tagging Tool and I want to create an "if" statement that would:

1- Limit access to owner
2- Limit access to members
3- Limit access to non-member

Any help would be appreciated! I know how to limit access to members and non-members using $client['id'] and !$client['id'] but I'm not good enough to figure out how to get the owner in photo.php

Thanks! :)
