I used my PhotoBooth program that came with my MacBook for the first time today. It's a fun program and I had a great time with it. However, the pictures, by default are 640x480 which is bigger than I want. I would like to set the program so that the pics were smaller by default but I am not seeing a preference setting for this anywhere in the program itself. Am I just blind or does PhotoBooth simply not allow you to set the size of the picture?
