Axel Pettinger to me:I think I've seen such spam mails. The image in my stock spam mail sample contains, apart from the text, many colored pixels.The test is to find two spams with the same "image text", and you will (almost certainly) find that the other components of the image are different, as described...
Ok. I've searched for it, found several similar stock spam mails which contained different colored pixels in the image, and then also one mail which was sent from the same computer mentioned before. It was sent two hours earlier. Almost everything was different but the image[1] ... Either the different colored pixels are not used to change the hash of the image or their creators change the image only from time to time or from computer to computer.
