Storing images on a CF memory
card
Your digital camera comes with 8 megabytes (MB) of internal
memory so that you can store images directly in the camera.
However, it also has a slot for an optional CF memory card. The
CF memory card allows you to expand your camera’s memory so
you can take more pictures. Then, after you unload images to your
computer, you can reuse the card.
With a CF memory card you can also view and save images on a
computer that is equipped with a CF memory card reader, and
print images directly from a printer that has a CF memory card
slot.
