GD2 doesn't like this JPG...

[ConqSoft]

Any ideas? GD2 will create a black thumbnail for this image when it's uploaded into Gallery, using IM, it creates the thumbnail fine. vB shows it as a link if you attach it to a post since vB uses GD also. (when it should show it as a thumbnail on my site).

Has that image been photoshopped? I seem to recall that images from certain versions of photoshop have something loopy in the jpeg format that causes certain version of GD problems. Can you access you error logs and check the script output?
