Download Them All
Over 3500 High Definition 1920x1080 wallpapers in one giant bundle.
Download is updated frequently, so should contain almost all the desktops.
Each desktop image is 1920x1080, but since they're all made of blown-up pixelart, they're usually quite small in filesize.
At last count, the download was around 82Mb, which is a lovely size when you consider there's over 3500 desktop images in there.
