The goal is to make you look like a desirable celebrity. And to kiss the Yes girls and make it awkward for the No girls.
So choose a good picture of you, where you look a bit famous. None of us really did a good job on looking like a celebrity. But take the photo that has the most likes from girls on your Facebook/instagram, and filter it or whatever.
Or if you have photos taken by a professional, those will definitely work the best.
