I’m trying to display my photographs onto my TV from my camera (Nikon Coolpix) – I’ve used Photoshop 7 to alter the images and successfully copied the files back onto the CF card but my camera displays the "card contains no images" message. I know that the files are there and can read them from my PC – can anyone help please.

Thanks in anticipation.

I have had the same problem with my canon powershot camera. Looks like the jpeg decoder in the camera is only aware of a subset of the jpg specs, so it isn’t smart enough to decode anything it has not encoded itself.

Once you modify the image, the file no longer contains the so-called EXIF data (IIRC Extra Information Format) that the camera adds to each of its JPG (and RAW) files. Most cameras will not recognize a file that doesn’t contain EXIF data — and may not recognize files whose EXIF data indicates that they came from other cameras either.. For example, I have two Nikon cameras which use CF-cards and although the cards are interchangeable between cameras, neither camera will recognize the other cameras images.
