Fixed background image for screensaver?

Hi, a customer of mine uses NLD9 (~ SL91) and would like to use a company logo as the only screensaver image. The standard KDE screensaver doesn't provide for still images out of the box except a single-color one. How do I make the screensaver use a still image without having to write another screensaver app for xscreensaver? TIA!
