Facebook App - Select friend image and add fun elements

The application is one where the user will play with the picture of a friend, putting crooked beak and eye, and then posting this photo on Wall of a fanpage. Work as follows: user upload the photo of a friend, then photo will appear in the application along with several different beaks and eyes (created by me), the user will drag the images onto the photo by adjusting the size, and then you can post it directly in the company's fan page Wall.
