A Quick Tour of the Windows 8.1 Metro Photo App
From the Start screen, tap or click the Metro Photos tile.
The main screen of the Photos app appears, showing you the Pictures Library.
Microsoft is actively burying and killing Libraries in Windows 8.1. If you haven’t yet taken control of your Pictures Library, the only folder in the Library is your personal Pictures folder. What you see on the main Metro Pictures screen is a list of all the folders inside your personal Pictures folder, with a representative picture from each folder emblazoned on the front.
If you’re connected to SkyDrive, tap or click the down arrow to the right of the Pictures Library tile and choose SkyDrive.
Metro Photos likely shows you a very uninspiring tile that says, simply, Pictures.
