Remove all five screws found on the outer shell of the camera. You will find three along the bottom (see picture #1) and two more up one side (the side closest to the LCD screen).
You will find three more under the USB port flap and one more under the memory card flap. Remove these four as well.
Once all screws are removed, use a blue iPod opening tool (seen in picture #3) to carefully pry the back outer shell away from the rest of the camera.
