For the record, this is the hash:
f768deaef22da979abcfb73c9175b54d71fcf891666c5449c1969c07c3cc8920
I've downloaded the image and reuploaded to /test/ but I get the wrong hash. My theory is that the image server calculates the hash from the uploaded data (byte for byte) and then changes the metadata so that the downloaded copy is not the exact same. If this is the case then Q just verified himself beyond reasonable doubt. Can someone prove differently?
