Thanks chaps.....
.....OPF It's an SD card. There is an option when downloading for the camera to empty itself when the download is complete. I can't see how photos can recovered from the camera even though it has not been used since the download??
obg I'll try the freeundelete thing in a bit. Although I'm groping a bit in the dark as it says to download the prog to a flash drive then use it to check the "C" drive?
