To change your avatar, you should go to your profile page. The picture in the upper-left corner is your avatar. Hover over that and click the little Edit avatar link that will appear when you're hoving over the avatar. Then it'll have an option there to upload whatever image you want to use for your avatar from your computer. The help page at Help:Avatars may have more information.
