In the Store search bar, Leo had her type: Image Glass

Leo explained: “Windows 10 comes with the ‘Photos’ app built-in. It’s powerful—it can edit, make videos, and sync to the cloud. But it’s slow for just viewing a folder full of family photos.”

(Note for you, the reader: Other excellent, safe options in the Microsoft Store include (for power users) or FastStone Image Viewer —but Image Glass is the simplest.)
