Below are “artistic” photos sized to be used as “Wallpaper” for your computer … or “Desktop Backgrounds” if you’re using a Mac. They are in 4K … 3840 x 2160 pixels so they should look fine on large monitors and scale for lower resolution screens in Windows and Mac OS. Fine for Linux as well.
Just click on one you like and it’ll open in another window in your browser. You can then just drag it or copy it to your computer.
