At the top of this page find the "head & shoulders" icon on the right side. Hold your cursor over it and a drop down menu should appear with your member profile settings. Click where it says AVATAR for instructions on adding a custom image. You'll want a square image a minimum of 200 x 200 pixels. If you use a larger image I think it will automatically downsize it for you. If the image isn't square your avatar may appear distorted.
