I have five images that fit in the size restrictions. Just save whichever one you want to use (if any), and then click profile, click edit options, scroll down to change avatar and click it, and then simply upload the custom avatar. You MUST have 15 posts or more before you can specify the custom avatar, but that's not exactly difficult to do...If you don't like these, the image must be no larger than 65x65 pixels.
