Yes its within my set sizes:

Heres the image im trying, but i've tried several others:

I did notice though that when I upload from my computer that i can still upload an image exceeding the size and it seems to automatically resize it. Just fyi.

I dont see anything related to this in my servers error logs either.

EDIT: So I came across this bug in the tracker: http://tracker.vbulletin.com/browse/VBIII-11010. This states its for vB 3.7.1 and a fix was uploaded and it was supposed to be fixed in 3.7.2. I downloaded the replacement class_vurl.php and tried it out and it seemed to of worked....but im using vBulletin 4.2.3. It seems a bug has reappeared or..?
