Go to ImageRecall.com and download their trial software.
You can get up to ten images back. If that works purchase the software.
One word of advise, do not use your camera with that memory card any more. Use another card for new photos.
Use the original card with ImageRecall.
Image recall works!
Do you have a card reader? Image Recall only works with a card reader and not thru your camera.
I had over 350 images restored with Image Recall from my photo trip to Turkey this past May.

Hello everybody,
I am very, very tensed and upset now. Last week I had a wonderful tour of my life in Paris where I shooted around 150 beautiful remembering pictures from my new Sony Dsc-V1. When I was back, I checked all those photos in my computer and found some with low brightness and contrast which I tried to fix in Irfanview. I've never worked with this software before.
I downloaded the photos to my computer and started editing some photos. Then I reloaded those edited photos back to my camera and found error that said "File Error" on my camera. I tried each and every variations and combinations to get back but couldnt. Then again I tried to download that specific "File error" photo back to computer and saw that it works well and I can see the photo without any problem. My biggest mistake was that i just didnt take a backup of original photos. Now I have around 116, 5.0 megapixels photos in my 256 mb memory card. Whenever I browse those photos on my camera, I can see the photos that were not edited and the photos that were edited I see as a "File Error".
I want to upload those edited photos to camera's memory card coz i need to develop in the local shop on hard paper. Kindly help me to get those edited photos from irfanview to my camera.
Any suggestions or advices are warmly welcomed.
Thanking you in advance
Avishai.
