There's websites with them, or you can make a picture reallyreally small yourself.

On User CP there's a section for uploading an avatar pic. You can choose from the stock or upload your own, but it has to be 50x50 pixels.

User Control panel -> Account settings(?) -> Edit Avatar -> Must be 50x50 -> upload -> ?????-> PROFIT!!!
