The simple solution: hide your desktop! At this point the little tool Desktop Curtain comes into play. It lets you completely overlay your desktop with an image, or change the background image and still display your desktop icons without the need to reconfigure your desktop settings: after the presentation simply quit Desktop Curtain and your previous desktop is magically back.

To access the settings dialog you can right-click on the desktop after Desktop Curtain got started, or relaunch it.

But I have to deduct 1 point for having to drag & drop a new image into the settings window instead of using a default file selection dialog.
