You want to use FvwmBacker. Take a look at question 6.6 in the
fvwm FAQ:
----------------------------------------------------------------------
6.6 How do I set the background with fvwm?
A: Setting the background image is not really part of the window
manager. If you are using one of the Linux distributions,
most likely, some part of the distribution is setting the background
for you.
There is a program that comes with fvwm (xpmroot) which you can use
to set the background to a pixmap. Other programs like "xv", "xli",
"xloadimage", and "display" are more robust, they can put most common
image types on the root display.
If you just want a static image on your background, you might invoke
one of these programs from your .xsession or .xinitrc file. You can
also invoke one of these programs from the InitFunction in your
.fvwm2rc.
The fvwm module FvwmBacker can be used to change the background
depending on the desk you are currently on.
