Is it possible to download spreads to use as a wallpapers?

I see these spreads and they look good to be used as wallpapers, but they're two pages. Is it possible to make them into "one page" and download it for using as a wallpaper?

Some of the spreads have been made into wallpapers for download here.

Oh, wow. I didn't know someone from FAKKU actually made them. Thank you!
