If you're on Windows, I quite like Splash![0], it's an app that automatically loads pictures from Unsplash depending on keywords you choose.

Thanks, I didn't know about Splash, and I like it! Too bad my system admin disabled the Microsoft store.

If you can get hold of the .appx file from another source, you may be able to install it via powershell.
