Windows Personalize wallpaper setting (Center, Fill, Fit, Stretch, Tile, Span)

[samueltsoi888]

Hello , 

I would like to deploy the wallpaper via Ws1, but does anyone know how to change the wallpaper size setting?

(Center, Fill, Fit, Stretch, Tile, Span)

and May I know WS1 can push the wallpaper to the Mac book?

Thanks.
