It is really easy to create a wallpaper slide show of your favorite family snapshots in both Windows and Mac. First up, we tackle Windows. To view the Mac tutorial, just scroll down or click here.
Windows
In Windows 10, click on ALL SETTINGS choose Personalization. Choose Desktop Background Slide Show, and choose a folder of your pictures. You can now select all the pictures in the folder, or just choose your favorites. Next up, decide whether the pictures will FILL the screen or be centered, and how often you want them to change. I have mine set at “FILL” and “Shuffle every 10 minutes.”
Mac
On a Mac, the process is very similar. Right click on your desktop, choose “Change Desktop Background.” Select a folder of pictures, and then choose “Change Picture” and select your rotation time from the dropdown.
