I don't know about other people, but I prefer taking photos of my animals in the best looking surroundings in or around my home, if that is not possible I still would never put them where it looks the worst. Admittedly I do presume when I see a photo taken with such backgrounds, that the rest of the surrounding is no better. And to me knowing about what is safe surroundings to keep your horse in, is part of basic horse care knowledge.
If there was/is a prize for using sales photos of your horse standing in the most awkward positions, who ever is selling this mare should have a good chance of ending up high in the prize list. And if I was confused after seeing the first photo, I'm even more so after looking at the second, does two bad photos makes a horse look better, than if you had only decided to use one of the bad photos?
