For a pic, you upload a picture by clicking gallery and going down to "upload picture." Then you click on "User CP" and "Edit Avatar." Scroll all the way down and either find a file on your computer or copy-and-paste the URL to a pic you like. For the avatars with the people on them, go to User CP and Design Avatar and just get started. ^^
No problem, and thank you. ^^ You can select a picture on your phone and go to options, then send. You then put your email address into the recipient box, and send it. Not all phones allow this, though.
