By clicking on sender's image in chat message you go to the sender's profile (this profile was either entered directly on NeoYou or was imported from some social site, like Facebook). There you can see who the person is and use cool tools (IM, Call, SMS) to communicate directly to that person. Note the send photo tool. You can take your picture on the spot and send it to a potential date. Beware that you can't hide too long behind a fake shot - if they meet you after movies they will see the face was not yours.
