Usually you can get them on a computer if you use a cord that has a "B" on one end and regular usb connection on the other. The computer will pick up that the camera is attached and will install drivers (depending on type of computer) to give you access to the camera's internal memory. If you have a card installed, you can remove that card and insert it to the computer using a card reader unless the computer has one installed on it.
From there you should be able to just click on the cards folder and get your pics.
