It appears that someone using the IP address 83.255.139.35 requested deletion of the image on 31st December 2006 but did not give a reason, so the deletion request was removed. I expect you would be successful in getting the image deleted if you put the deletion template back on the image page with an explanation of why you think it should be deleted. From what you say, I gather there is already a good quality picture of the same person, so it seems sensible to remove the bad quality one.
