Currently there is no easy way for the user to set a custom background (wallpaper) for Dom0 desktop. Of course, one can try to copy JPEG to Dom0 using tricks with qvm-run, but that is an unsafe operation (and this is precisely why there is no tool for file copy to Dom0).
Better idea is to let the user set the wallpaper in one of the AppVMs (they have the same screen resolution), using the already existing mechanisms (e.g. right click on some JPEG and choose 'Set as wallpaper'). Then, the gui-agent should inform the guid that the current AppVM's wallpaper should also be displayed in Dom0 as root window.
This way we allow for custom wallpapers in Dom0 without introducing any security problems.
