What's in a picture?

There have been at least a couple questions asking people to show pictures of themselves. I’m wondering what people get out of it? I know I’m curious about people, but I also know I’ll never meet any of these people in real life. The online world, for me anyway, is a fantasy world, and fantasy, I think, is best left in one’s imagination. Too much information limits you.

However, I’ve noticed what I think is a noteworthy trend in those who do put up pictures. Those who put pictures up are mostly young. The women all seem to be very good looking. I’m not going to venture an opinion about the men. Men don’t generally look good to me.

What do you get out of pictures? Why do you want to know what people look like?
