Short Hairstyles for a "big" Round Oval Shaped Head?

Please , PLEASE help me .. I'm always picked on for having a big head but I'm trying my best to find hairstyles that are SHORT to fit my face because of my abnormal head shape.
Heres me (but I have extensions) : http://imageshack.us/photo/my-images/708/cfyfdnmt.jpg/

You are beautiful. I don't understand why you would be picked on. Go to a salon and speak with a stylist,together you will pick a style that would suit you and your life style. Good Luck.
