It's most likely that if the above post didn't fix your pictures that this will; the pictures are still in your pictures folder, correct? they're just not showing up in your album, right? if that is indeed the case, go into your pictures library, at the top right (under pictures library) it should say Includes: 1 Location, if it says that it includes 0 locations, don't worry we'll fix that. Click on the blue text, and select the item in the grid (if one is there) and select the "remove" button to the right. now, click the "add" button and navigate to your user's folder ( C:\Users\YOURNAMEHERE ) and select your pictures folder (do not double click) and click the "include folder" button. There you go (: should've fixed everything right up.
