Can I retrieve photos from a digital camera without the program cd that came with the camera?

I have a borrowed digital camera with the computer plug in only. Is it possible to get the photos out of the camera and save on my pc. Can I do this while not deleting the pics that were already on the camera so as not to delete photos not belonging to me. If this requires a download, where can I get it free. FYI...first time digital camera user with no other material brochures, training, etc.
