If you're having trouble, just go on picnik, upload the picture of the character you want to make a smiley out of, go on Crop, change the constraints to Square (this is really important), crop the character's head, confirm, and then resize to 50x50. Save and share, JPG compression quality (best), save photo. Then upload on tinypic or whatever uploading site you use.
