If you're interested in pictures of bald-by-choice folks, I can't recall any site as packed to the brim with photos as Barbering and Balding in Oz. This site is packed from end-to-end with hundreds of pictures. It's designed with broadband in mind; pages are large and take a while to load on a slow connection.
They've also got a page of balderized photos. The site's author accepts new photos through email, so if you want to see your photo 'balderized', send it on over. They can also do other virtual hairstyle changes.
