I have a problem that must be common with this camera. I'd like to upload .jpg images to the camera that were not created by the camera, instead images scanned from older slides. Then I can show them on my TV set using the A70. Canon Support has told me that this might be possible using a CF card reader, so long as the size is supported by the camera and the format matches the JPEG files created by the camera. Does anyone have experience with this. What CF card reader would be right? What are the proper sizes? What is format within the JPEG family? Thanks!
