Hey Debbie,
I tried to find the thread where this was addressed, as I had this issue with my previous picture. I couldn't find the previous thread, but you have to start with as close to a square sized picture as possible, if you don't want the top of the photo chopped off. Crop some of the bottom of your photo off and you're photo will be better centered in the thumbnail version. I think it looks fine as it is, though, as only a small part of the top of your head doesn't show in the thumbnail and some of the photos Julian took of us were already shot that way...tres artzy! ;0)
