How do you download photos from camera to my PC?

This really depends on what kind of camera that you have. Some you need a USB cord that plugs into your USB drive, and it will assist you when you need to upload them. These instructions, again, depend on your camera and PC model. If you have a camera that uses a data chip, it would plug into the K drive of your computer, which is usually below the USB drive (it is on mine.) It would look like a thin, long plug that is on the side of your computer that would look like the side that you plug the chip into. Again, this depends on your PC, camera, and your method of uploading the pictures.
