D300 as an photo viewer
Is there a way to view NEF files taken with a D100 on a D300. Or even JPG files on a D300 with the ability to zoom in?
I have tried to copy D100 NEF files to the right folder and read them in the D300. It displays the picture but when I try to zoom, I have a message: "Cannot zoom in on this picture." I have tried to copy some modified JPG and it would not even display the image...
Thank you for your help,
edit: I own a Canon but I am trying to help a friend who has a D300 and had a D100
