I have a Canon Power Shot A720 and used the card reader to import photos into the organizer. Now when I go back to erase some images from the camera I see many, but not all, of my ‘once’ images blacked out with a grey/white box in the center & a yellow question mark. Under the box it says “incompatible JPEG”. What does that mean? It’s never happened to me before, but I usually import my images directly from the camera.
