This page will let you set Wallpapers of Will And Gareth. - Just:
1) Right click and select "Set as Wallpaper"
NOTE: You can't do the above more than once because if you do, that one will overwrite the first one! e.g.) Selected a
Gareth wallpaper, and then selecting a Will Wallpaper will overwrite the Gareth one.
2) And it'll be on your desktop!
