So I've been struggling with this program since I got it installed. I finally started getting it all sorted out, and when I click on a thumbnail of an image that has been uploaded (by me), it takes me to the admin config page. When logged out, it obviously gives you the "you do not have permission to access this" blah blah blah. But what I don't get is why clicking on a thumbnail to view the larger photo, that it takes me to the config page.
Try it for yourself. Gallery is here> http://www.pa-tacomas.com/coppermine/index.php
