Well, figured it out. Very weird; I had randomly pulled a couple of images (a jpg and a png) from the net to test with. Somehow both images are corrupted somehow? They could not be loaded into Paint either, although they of course look fine in the browser.

Grabbed another image and now things work fine. Have never seen images be messed up like that:(
