^ that.
then, make it a 128x128 square and save it. upload it. there you go.

Here, i did it for you:

Hey there, you'd be much better off making a request in the request's board of Arts and Textures. Simply pasting a picture like that onto a square won't look good as a head. It won't be mapped correctly see the avwave's nice, image heavy explanation. If you can't get that then try one of the many free head shops around.
