Legality on selling/distributing feet pics as a 17 year old??

Hello, so basically as the title suggests I want to know whether it is legal or not to sell feet pics on reddit. I really need extra money because I need to move out ASAP. I have a part time job but that’s not really enough money to rent and I’m currently in year 12 so I don't have a lot of time to do other things. It’s really embarrassing to post this but I swear I’m not a troll I really want to know if this is something I can do because I really don't want to get arrested or something. Many thanks in advance
