This must be IE image rendering problem. I have downloaded a broken image under Firefox, and then loaded the image by drag and drop in IE. The same result - please check the screenshot. When I open the same image with Firefox, it's rendered.
This explains why Jacques solve the problem by resizing - the application which resizes the image saves it correctly, with all the image headers and so on. You can try the same.
