A seventh photo has appeared on the 1-18-08.com site! It looks like a picture from one of the Chuai news videos! There is nothing hidden on the back :(
UPDATE: the link above is to our mirror of the original 1-18-08 site. DO NOT go to the original 1-18-08 website anymore. The domain expired and is no longer controlled by Paramount, and someone else snatched it up to run ads with malware.
