Just wondering if anyone has seen this problem before and may be able to offer some advice on whats wrong?
The gallery is at
http://www.stencilrevolution.com/photopost
Where you can see that anything uploaded recently has a distorted/pixellated thumbnail. If you click on the thumbnail, the fullsize image that is displayed is fine, it just seems to be the thumbnails that are getting distorted on upload.
Server is using GD2 for the image processing.
Any help would be greatly appreciated.
