I used to have a strict rule that no pic meant no chatting. Recently I received an email from a no pic profile who insisted politely we chat and said he had a webcam. He has to be one of the prettiest most chisseled young men I've ever seen. Point being, I don't trust pictures, outdated and such, but webcams would be the way to go; ask if he has one before you send him away. It'll be more recent than any picture. Good vibes.
I have found from past experience that sometimes the guys without the photos are the ones I am really glad I met.
I'll go to the meeting without any expectations since I haven't seen a photo and when the guy shows up with a beautiful smile and sparkling eyes, I melt! Last three dates I had I did not see the pic before I met them and they were all great.
So I won't discount anyone just because they didn't post a pic.
BTW, I've met guys who posted pics that didn't look anything like the pic. One guy's pic was from 20 yrs ago.
