Digital photography

you idiot.

the images are still there, the sandisk software you get free with their higher end cards will retrieve them as will any data recovery software . all that's wiped is the registry, wouldn't surprise me if there are images on there you thought were long gone*

*as long as you don't shoot loads more pics on the card

I have tried that Sandisk software - admittedly after shooting on the card lots more - and found images from like 6-9 months back but not the recent ones.
