Jess, try the following link to find out where your files are and then move them back under "Pictures". Mine were hiding under "Documents".
If your problem is like mine, once you move them you will have to right click on every picture, select "Properties" , uncheck "Hidden", click "Apply". You can tell which ones need to have this done because the icon in front is not highlighted.
With any luck, someone much more savvy than I will have a shorter way to do this. My files went screwy after I downloaded the most recent version on Internet Explorer. MY "Favorites" also disappeared and had to be redone. Such a pain.
With all of our running and all of our cunning, If we couldn't laugh, we would all go insane...
