Pictures won't open

Try opening the pictures in a different applicaiton.  For example, try to open them with Internet Explorer.

Try clearing out your temporary folder.

First close all relevant programs and then from the command line execute the following commands:

rd %temp% /s/q

md %temp%

To get to the command line press the Windows + R key, type cmd, click OK.

Try installing IrfanView. It's a wonderful program and I use it a lot. Its batch mode is great, especially for things like shrinking photos to email size. Download Irfanview from

If it works, make sure you set it to always open your pictures, instead of the useless Windows Picture Viewer.

You may have to use file recovery software for your camera memory card. From your picture2.gif only part of the image is being disolayed.

But, Explorer can see the whole picture, otherwise it could not create icons for them. So I'm hoping there are no problems with the files or the card.

check to make sure your video card drivers are up to date

I see that you previously asked about recovering deleted images from the same or different camera:

and that TestDisk or PhotoRec apparently worked for you on that occasion:

I have tried neither of these, and so cannot comment.

Perhaps you should also add the "Digital Forensics" Zone to your question:
https://www.experts-exchange.com/Security/Digital_Forensics/
The experts who frequent that zone are obviously the people who are best equipped to know the best methods of this type of data recovery, because that's how many of the top people there make a living.

Here's a file recovery utility that is easy to use: MiniTool Power Data Recovery

Do you have any feedback sharpapproach?

My apologies for the delay.  I had a family emergency that has kept me away.  

Recuva worked perfectly!!!!!  
Thank you BILL!

Wow! That really IS good news.

I assume that you have verified the integrity of the images by opening them all (I know it's a laborious task) in an image viewer, not just seeing them in Recuva's "preview" window?  Just making sure, because "previews" usually use the embedded thumbnail rather than the main image data to display in much the same way as the Windows Explorer thumbnail view is really just a preview.

Clearly something has gone wrong either during the transfer of the images from camera storage card to computer hard drive, or something has later corrupted the images whilst on the hard drive.

To try and eliminate possible corruption during file transfer, I think you should consider setting whatever software that performed the transfer to COPY the images and NOT to delete them from the camera until after you have verified that the copied images are intact.  Maybe also buy a new camera storage card and use the camera's menu options to format it prior to use, just to eliminate the possibility that the storage medium corrupted the images.

I also suggest that you back up your documents and images to a good storage medium like a 2nd hard drive or even burn to CDs or DVDs, and then run the Windows Disk Error Checking utility.  Right-Click C:\ Drive > Properties > Tools > Error Checking.
