All of the social and dating websites have a place to post pictures. And you are encouraged to post at least one photo of your self so that people know what you look like. In fact, if you don’t post a photo of your self on your dating website you probably won’t attract anyone.
Now, while you may not be a fashion model, it is still better to post a picture of your self and let prospective dates decide for themselves than to not post one. I can honestly say that I have never rejected a potential date because she was ugly. But, I have rejected prospective dates because they did not post a picture. Let’s face it, dating web sites are impersonal enough as is, so photos help to make them a little more personal.
