saveing a gadget with a wall paper

I would like to know the answer as well. I've tried attaching the image to the object. You know, when you go to the 'summary' tab and click on 'custom files', but it didn't work. I just included the wallpaper in the zip file instead.

This was not really the way you wanted to go about it, but if it helps, using Theme Manager, which, as you know, also belongs to Object Desktop, you create a suite including that wall and also including a desktop THEME you made including the widget (might work with gadget, too), calling up that suite after saving it from Theme Manager would simultaneously switch on the wall and the widget.
