Igor,

I found also 2 sample of code to set wallpaper under Windows and MacOS :

-
https://stackoverflow.com/questions/5468074/programmatically-changing-desktop-image

For Windows, we cross compile with MXE (based on Mingw)
For MacOS, we use Macports.

For both non Linux, i'm able to test on my computers.
