create a wallpaper concept for each new relase, as mac does

create a concept for the wallpapers that will come in each new release... like mac does, they include some related wallpapers (they relate them to the name of the relase) in mint's case i could be just a theme even if it is not related to the name of the release... for instance, in the new relase include snow scenes, or city scenes, or water scenes or so... also please have a look to this ur: https://unsplash.com/ it is full of grate free grate pictures that i use for my desktop... some of them are really grate.
