Outside of real Yeshivish circles, in the last few years, I havent seen a girl get a date, unless shes willing to give a picture, if asked. If the girl doesnt give a picture, they’ll find many other pretty great quality girls who will.
Is it right? Maybe not. Lots of things in the world are wrong.
If you feel so strongly about it, tell a well known R”Y to make a new Psak, and say its assur to ask for pictures.
You only hurt yourself if you dont give a picture when asked. Unless you want to wait and wait and wait… which is not good.
