@Alex I’ve tried this before and honestly Google Images or TinEye is your best bet. Upload the pic to Google’s reverse image search, sometimes it finds the same photo on IG or other sites. I actually used it last month to track down an old classmate’s profile. If you end up guessing a username, Detectico can do a reverse username lookup to see where else it shows up online. It’s not a magic photo-to-profile tool, but that combo worked for me. Good luck!
