Edit your profile->click on:Your avvie or Change my profile

go on the bs site. then click " edit your profile" then once
that is done, click on the "change my avatar" or " add an
avatar" then chose a picture that has been downloaded on
your computer.

Once you log in, below where it says, ''Welcome, Simba and
Kiara!'', you will see ''Edit your Profile''. Click it, and
once it loads you should see a place called, ''Simba and
Kiara'' in large yellow letters. Below there it should say
something like, ''Add an Avatar''. Click it, and upload a
picture you want as an avatar. Note that avatars WILL NOT
upload on TLK Source, so go to Balto Source and do the same.
Also, it MUST BE JPG OR GIF. Good luck.
