Wallpapers for Purchased Books

I'm sure I'm not the only one who'd love to see wallpapers for books that we purchase. Would it ever be possible for each book to include a digital wallpaper download? Even if the wallpapers were only the covers, just without the branding, it would be super cool.

Usually the books come with posters inside and there are digital downloads of the books so you can just set one of the posters as your background

A good number of tanks come with a poster. so if you buy the physical you'll have the digital book as well, just look for the page you want as wallpaper and voilá.
