The only photos of food I care about are customers posting them from the restaurant to for example google maps. I guess these can be gamed/smurfed as well, but I think mostly not, and they'd have to prompt for a bad photo from a mediocre phone camera taken by a person not caring much about framing.
True! Most of the time i don't remember pictures being there at all (especially in menus), which is (imo) still preferable to having generic AI generated images
Many if not most restaurants weren't using real photos of their actual food long before gen AI was a thing, especially in promotional materials.
