Recovering photos question! :"(?

I tried Recuva and it was able to put formerly deleted images into the folder I specified, but there were no previews for them, just this cartoon of a landscape(if you're using Windows, you might be familiar with it) and when I double-clicked it, no photo appeared, and I also tried uploading it(just to be sure it worked), but it wasn't able to. :( What do I do? They're now back in a folder but they're as good as deleted files again.
