Anyone can post photos on the web for all to see. When I don't have the energy to do something more productive, I browse those photos and find fun, fascinating, and often titillating keyholes into others' private lives. When I find one photo that I enjoy, I look for related pix; so, for instance, if there's a photo of a girl getting her bottom smacked, I'll look for another photo that shows her face clearly. It makes the spanking photo three-dimensional.
Photos of women I've spanked are included in the relevant area, not here. The best example is the photoshoot from kate at The IF Photos.
There are nontrivial ethical issues at play here. People post their photos on internet share sites for anyone to enjoy. One could argue that I can't invade the privacy of someone who's posted a picture of his or her ass getting paddled in public by re-posting that photo. But I'm sure most of the posters don't realize that these photos may be re-posted on a kinky sex site, and some would not be happy to find them here.
If you are the copyright holder I would be happy to acknowledge your copyright or to remove your photos if you prefer that. If you are not the copyright holder, but you are identifiable and you would like the photo removed I will accommodate your request as well. Or if you want me to put your real name back in, or have me post more photos, that's certainly possible; send me a note.
