  Patricia HornAug 20, 2025
  If you're having trouble playing back images on your Canon Digital Camera, here's what to check: * If the images were shot with another camera or edited on a computer, they may not be compatible. Computer images that cannot be played back will playback if they are added to the camera using the bundled software program ZoomBrowser EX or ImageBrowser. * If the file name or location was changed on a computer, set it back to the camera's original file format/structure. * Avoid opening the SD card slot/battery cover while the power is on; close the cover and then turn the power off.
