It doesn't necessarily have to do with looks. If someone wants to meet, I expect them to share a picture of themselves. I've done it. I would not meet someone who refused to show a picture. It's about being honest and up front about who you are. If you can't be up front about things before you meet, there's a problem.

Physical attraction is at least half of a relationship. I post my pictures--recent ones. And I expect the same from anyone who wants to talk with me. I love eyes; they often reflect the personality hidden behind them. So I don't respond to men who message me, wanting to know more about me or meet me, unless they have a picture and a profile. I think I even state in my profile that they must have a pic/profile if they want a response from me. I've shown you mine, so show me yours too.
