Sorry; I missed this one earlier. One way to change the wallpaper
without delving into the registry is the SystemParametersInfo function. 
Try the following:

<code>
import win32con
import win32gui

WALLPAPER_BMP = "c:/temp/t.bmp"
win32gui.SystemParametersInfo (
    win32con.SPI_SETDESKWALLPAPER, 
    WALLPAPER_BMP, 
    win32con.SPIF_SENDCHANGE
)

</code>

The only thing I'm not sure about is whether it will survive
a logoff. If it doesn't I suppose you can always combine it
with the registry technique to make it permanent.
