I have no idea when it happened, but I'm a little peeved I didn't notice it sooner, or that perhaps someone would have pointed it out to me, but that might be reaching. Anyways, at some point the photo comments were deleted and an old copy of the script that creates them was being used, so that no new comments would be posted either. What irks me is that I know that there were random comments going quite a few years in there that are completely gone now. I can't even find an old backup of the .sql file that would have them either. So I guess there are comment-less pictures now.
