how to put a background image

Hi everybody,

 

Sorry for my bad english, I'm a french people. I've just discovered the
ion3 window manager, and I have some difficulties

to put a background image to my desktops. I have installed imagemagick
and trried to put an image using the display command :

 

azer@ramscan:~$ display -window root images/Bionix\ Wallpaper\ -\ Robot\
Sit.jpg

 

But it doesn't works. Any idea please ?

 

azer.
