Well I had some jpeg picture files in m computer, already in windows photo gallery for some reason, and I went to edit them via fix. I fixed some red eye and cropped the photo.. and pressed back to gallery, it supposedly saved. When returning to gallery and upon clicking the photo I just edited.... the photo is completely gone. Even when I go to the original folder of the photo...if I click the photo nothing comes up because it says the file is empty. I have lost 2-3 photos experimenting with this and have no idea how to fix it. Any advice/help please?

thanks
