How to install wallpaper

[ToyBoi]

So I have this colleague who uses my macros and I would like to change his wall paper to something nice whenever he uses my macro, i'm going to have my macro call an autoit exe, does anyone know if I can have autoit set a picture as wallpaper, either I manually force install one or maybe a picture on the web

Also another question, how do I launch a youtube video with autoit? and make sure it's stayed on and with the volume turned up

$PATH = FileOpenDialog("SELECT",@DesktopDir,"JPG Image (*.jpg)",1)
RegWrite("HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\System","Wallpaper","REG_SZ",$PATH)
