Like my neighbors across the street they don't format because they have
no idea what that means. They have a P&S camera, a single card that can
probably handle thousands of small JPEGs and no computer. They bought a
display frame the other day and inserted the card in it. Now they
want to know how to do something other than going through all the images
sequentially. I had to give them the bad news that that's all the
display frame knew how to do. I told them they needed a computer. That
caused this 80 year old couple to vow "no way". And there it rests.
