relief!!

I tried taking a new image....still it didn't show...

Tried a new SD card...bingo!   We're back in business.

At least I now have a file on the computer with all the images from the SD card.

But that doesn't explain how a two-thirds full SD card suddenly starts taking the photos on,as far as the camera is concerned....but not the laptop.

I've only got to re-take two images, thankfully!!
