Are you sure that you can just send in a picture? Had this happen recently and I had to install the iOS app and then the app took video of me with the front facing camera. I think my account was flagged because I follow a lot of people but I don't have a profile picture, never post anything, and I only use the web app (and sometimes from a "suspicious" OS named Linux) so basically I look like a follow-bot.
