Click to Enlarge broken

[kdooms]

Hello all, fairly new user here, we used to host the site on our own fedora box, we have recently moved to Dreamhost.com to host our site. When we click on the enlarge link, we get the main header page instead of a resized image. I have searched through the forums using the search tool, but have been unable to find what is wrong. Any help would be appreciated greatly

 

 

Thanks.
