Browser and wget load JPEG differently?

I'm stumped on this one. Try loading this image in your browser, and then save it to your hard disk.

It's a valid JPEG file at 11377 bytes.

Now try to download it with wget or curl. Only 11252 bytes show up, and the bottom right part of the image is missing.

What gives?
