Open File Explorer and navigate to the folder you had the pictures in. Right-click the folder and click Properties. Now click the Previous Versions tab. Hopefully you'll see the pictures there.

Good luck.
Ok, so I used the Snipping Tool on Windows 8 and saved like 7 pictures, and they can't be retaken. After navigating to the folder to preview them, I accidentally press Ctrl + Z, and the pictures were gone. I tried Ctrl + Y, but nothing happened. I can't find the pictures in the Recycle Bin either.
