Rose, if you are using a cable to download your pictures directly from the camera to the computer, you are wasting battery power and valuable time. For about $25 you can get a USB card reader. You remove your memory card from the camera, insert it into the reader, and insert the reader into any open USB connector on the computer. Once connected, the memory card appears as a removable drive.
If you don't know what kind of memory card you have, take it into the camera store with you so they can set you up with the right card reader. The Kits, Ritz, Wolfe chain of stores has readers at a very reasonable price. Don't let them try to sell you a more expensive one.
Good Luck. PM me if you have any questions.
