Help With Carbon Theme

I built my first gallery using this software, and so far it rules!! I'm the creative lead for an indie mmo and am trying to make a gallery to show our 2d/3d art. For some reason, when I click on a picture to view it, there is some php error that shows. I'm not sure if this is only with the carbon theme, or just my config of the gallery in general. But please help!

Also, i'd like to put the 2 sub albums of 2d art and 3d art as main albums so that i don't have to click the mechnet album. How can i do this (make the 2 sub albums on the same level as the mechnet/root album)?

Thanks a bunch to whoever helps!

edit: The link to the gallery is http://oev.jeffman.net/gallery/main.php and i've fixed the two subalbums to root album problem. Wow, this gallery is the MOST user friendly peice of software i've ever used in my entire life! Still need help on the img error though.
