Nikon RAW files store a full resolution jpg version of the photo inside of the RAW file (this may be true of other RAW formats too). I had a similar problem to what's described in the article a few years ago, and for photos that were damaged which I didn't have backups I was able to get the jpg out of the RAW by running this command: exiv2 -e p4 image_name.NEF Apparently this jpg is what the camera shows on its backscreen when you're previewing the image/RAW file.
