Personal wallpaper library with three imported landscapes and a Mountain Lake Fill preview for the main display

My Wallpapers - Refresh Time starts with an empty personal collection. This guide walks through importing a folder of landscape photos, reviewing the selected images, including each photo in automatic rotation, and previewing one photo for the main display. Nothing is applied to the desktop during these steps.

  1. 1.Review the photos to import

    Choose Add Folder… and select the folder of photos you want. In Review Wallpapers, check that the three photos are selected, then choose Add 3. The photos are not in your library until you confirm the import.

    After confirming the import, your Library lists all three photos. Select any thumbnail to view its preview without changing the wallpaper currently on your desktop.
