Forum loading excruciatingly slowly

[Arjahn]

Hey guys, lately I haven't been using the forums much because whenever I try to do anything on the forums, it takes absurdly long, like 30+ seconds per page load long. It's not my machine either, everything else loads perfectly fine. The forums have the following error on top of the page

Spoiler

[PHP] errorHandler->error
[snip] 101 getimagesize
/global.php(530) : eval()'d code(9) : eval()'d code 5 include
/global.php(530) : eval()'d code 9 eval
/global.php 530 eval
/forumdisplay.php 21 require_once

Can anyone help me out? Also, sorry if this has been posted elsewhere, it's just so damn painful to read through stuff on the forums now -.-
