They use something called PTP - picture transfer protocol, rather than the more common systems used by digital cameras. Have you tried using gphoto2 to get the images from the camera? It should be able to retrieve the photos for you without locking up the system. My daughters Canon (different model - same PTP) works with gphoto2 but not with other apps. If you still have problems, even with gphoto2, I can grab her camera and do some experimentation ;) Mark -- The Mailing List for the Devon & Cornwall LUG http://mailman.dclug.org.uk/listinfo/list FAQ: http://www.dcglug.org.uk/linux_adm/list-faq.html
