I’m against the boys seeing pictures before they go out. Beauty is in the eyes of the beholder, and it is very subjective. Therefore, to make that judgement based on a picture is not being fair to both the bochur and the girl.
If it were my daughter, I would say no to a bochur who wants to see her picture first. I understand that there are some bochurim who have been “burned”, when people told them “oh, she’s sooo pretty” etc. But too bad. In the circles that I am in, this is not something I would consider as ok. I would want him to ask about her middos, personality, hashkofa, ideals, and goals in life, and see if those things seem to be compatible, before deciding on going out.
I highly doubt that one photo could give all the information they need–even what they really look like.
Hatzlocha to your daughter, and may the process of shidduchim be pleasant and short for both of you.
