timthumb.php trouble

[Kuujiryo]

I've searched around the forum a little, and came across many suggestions for thumbnails not displaying. I've added the cache folder, I've messed around with the permissions a lot and still no result. However, when I go to the thumbnail URL, I'm getting some errors, followed by a bunch of random characters, followed by more errorness.

My website's locked at the moment while I set this theme up (don't want people looking at it while it's incomplete) but I think that's everything that needs to be known.
