Recently I stupidly deleted some photos I shouldn't have. I used a [program](http://www.piriform.com/recuva) to recover the photos, some of them came back in a corrupted condition like below with grey areas.

Any idea on how to fix this? The information is clearly there in some form, as when I view the photos with Windows Photo Viewer, the complete image is briefly shown for a fraction of a second while windows is generating the preview.
