It doesn't really matter how many photographers there's been. She's not just getting photos taken by random people. It's profession work done by professional people. I'm sure there's some outtakes or video or something that has nudity in it, but the photographers can't just leak that stuff out. Obviously she knows who was shooting each set.
If something got out it wouldn't just be a professional disaster, but a legal and possibly criminal incident. If something got out through negligence it would ruin the photographer's career and expose them to financial damages and penalties.
If it was from a partner, an ex, or an intentional leak from a photographer it would probably also violate some sort of revenge porn laws, which could lead to jailtime or a sex offender registry on top of the financial stuff.
Obviously no professional is going to do anything like that on purpose, and they're going to take steps to not leave any sort of raw data or outtakes on a cloud server.
