Setting wallpaper

The only thing that has eluded me on fluxbox is setting a wallpaper.
I have the following in my init file 

  session.screen0.rootCommand: fbsetbg -f  ~/.fluxbox/backgrounds/Fluxbox_Wallpaper_04_by_vermaden.png

  (see http://fluxbox.sourceforge.net/docbook/en/html/chap-bg.html)
 
But no wallpaper appears. I see no errors in .xsession-errors or the
fluxbox log file.

 Alternatively I have place the following in .xinitrc
   fbsetbg /home/tim/.fluxbox/backgrounds/Fluxbox_Wallpaper_04_by_vermaden.png

1)Do I need to do something else?
2)Is there some other configuration that might interfere?
  overlay has no executable code.
