Go to your 'user cp' which is located at the top of the page, the second purple button.

Go to 'Edit Options' which is the third option in your user cp.

Scroll all the way down, where it says 'Avatar'.

Click on 'Change Avatar'. This will bring you to another screen which will say Edit Avatar.

At the bottom it will say 'You can upload an avatar from your computer' -- then it will have a section and a button that says Browse. Click browse and select the picture you want from you harddrive.

Click Submit Modifications.


Your avatar must be 60 x 60 pixels. If you don't know how to resize your photo to 60x60 pixels, just ask and I'll help you with it.
(I can't resize animated avatars though, sorry.)
