Therein lies the potential problem. How do you know that there are no pictures of you or your rig on the site? Have you looked at each and every one of the hundreds of photos Billy has collected?
I think Billy is on the right track to obtain permission for posting photos on his site. The problem is that he's starting awfully late in the game. IANAL but I was in a previous existence a semi-pro photographer and I knew enough about copyright law to get myself in trouble. If someone openly posts their photos on the Internet with no disclaimer, then the pictures have effectively been released into the public domain and anyone can copy them onto another site, and even use them to make money, and the original photographer has no valid claim for compensation.
But ... I don't know how careful Billy was to check each web site he copied pics from for a copyright or "all rights reserved, do not reproduce" notice. If any of the pics are from sites with such a notice, those pics were NOT released into the public domain and nobody has a right to copy or use them without the original photographer's express permission. Simply posting a note saying "If you don't want me to use your pics send me an e-mail" doesn't satisfy any legal requirements. The legality is that if a photo came from a source where the owner's copyright was declared, posting it on another web site is illegal and a "let me know" notice doesn't make it less so. That's a geat gesture of goodwill and good intentions for non-copyrighted photos, but it doesn't protect Billy if he has any copyrighted photos on his site.
