Saw the website. The man's irreverence is egregious. ("Watching stand-up comedy," "pirate image.") Swordmaker, what are your thoughts on the length discrepancy of the front and back images? He mentioned it on his faq page, I don't believe I've ever seen it discussed here. (Could be wrong about that!)
The differences go away when you map the body onto the draped cloth. Experiments conducted by researchers who placed human volunteers on shroud like cloths, mapped the contiguous points of their bodies vertically collimated and found similar length differences.
Prof. ssa Emanuela Marinelli- Co-authored with Alessandro Cagnazzo and Prof. Giulio Fanti a study on this very subject: Computerized Anthropometric Analysis of the Man of the Turin Shroud . This is a PDF file and you will need Acrobat Reader to read it.
I assure you that forensic anthropologists have examined the image on the shrouud and are convinced it is of an actual human body.
