User PC crashed, yet I was able to pull data off of drive before reimaging drive. All data and pictures copied back to user's drive and everything but his pictures are fine. It states Windows Photo viewer can't open them but Photo viewer can open other jpegs copied over for testing. All jpeg files have size attributes, etc. I notice that when I try to re-associate the file type to say Paint/SnagIt/Infraview that the selection for 'Always use this program for this type is greyed out and cannot be changed. However when I change it to these programs it still won't open. I'm not buying that 20 GB of pics are corrupt while 30GB of data is fine, as well as jpegs that were in other locations are fine, yet if they've suffered corruption is there a way to repair them.
