Openbox doesn't have any specific support for it. In fact openbox has no 
support for wallpapers at all, but it doesn't use virtual root windows. 
This means that when you change desktops, you are still looking at the 
same desktop, we just unmapped all the windows on the old desktop and 
mapped the ones on the new desktop.

You could have a desktop type window on each desktop that simply displayed 
whatever you wanted, and it would have that effect. Note that having that 
large images open at all times uses some memory:

You have: 1680*1050*3 bytes
You want: MiB
 	* 5.0468445

If your machine is under some load, those images could be swapped out and 
desktop switching would be slowed down.

I'm not aware of any such existing program, and you are maybe the third or 
fourth person asking for it ever, so I don't think there is a big demand 
for it :)
