Here is how I'd go about investigating that:

1) Type "graphical imports" anywhere. Select it. Press Ctrl-Shift-E.
2) in TheWorldMenu>>helpMenu you find { Imports default . #viewImages}
3) inspect "Imports default"
4) inspect "imports" inst var

You can find out just the same. E.g., when you select an image in a file list, you can click the "background" button to set it as background. Now you just need to find the code for it: "background for the desktop" is part of its help balloon. Type that, press ctrl-shift-e, follow the implementers chain from #serviceImageAsBackground to #openAsBackground: and there is your "magic incantation". No magic at all ;)
