If you ask the makers this question the answer is that this is not supported. The industry so far does not support use of the camera as a PMP or viewer for pictures from other sources. I'm encountering new users that are in disagreement on this and demand a fix. As it stands, the camera is not a PMP or viewer so it's not something we expect in the product.
I put a SD card that I took pictures from another camera (Canon T3i) in the coolpix S4000 and all the previews are blurry anyone know why?
I tried reducing the size on the image and doesn't make a difference.
