How to make script that sets new wallpaper? If I just overwrite registry values then I have to log off and on to see new wall paper but how to I write script that applies new image instantly?

I found function but problem is: It cant set *.jpg image as background (it worked fine with *.bmp) anyone know what's wrong?

Global $REG_DESKTOP = "HKEY_CURRENT_USER\Control Panel\Desktop"
_ChangeDestopWallpaper("C:\Documents and Settings\rain\Desktop\pildid\Picture 001.jpg",2)
Func _ChangeDestopWallpaper($img, $style = 0)
    Local $SPI_SETDESKWALLPAPER = 20
    Local $SPIF_UPDATEINIFILE = 1
    Local $SPIF_SENDCHANGE = 2
    If $style = 1 Then
        RegWrite($REG_DESKTOP, "TileWallPaper", "REG_SZ", 1)
        RegWrite($REG_DESKTOP, "WallpaperStyle", "REG_SZ", 0)
    Else
        RegWrite($REG_DESKTOP, "TileWallPaper", "REG_SZ", 0)
        RegWrite($REG_DESKTOP, "WallpaperStyle", "REG_SZ", $style)
    EndIf

    DllCall("user32.dll", "int", "SystemParametersInfo", _
            "int", $SPI_SETDESKWALLPAPER, _
            "int", 0, _
            "str", $img, _
            "int", BitOR($SPIF_UPDATEINIFILE, $SPIF_SENDCHANGE))

    Return 0
EndFunc   ;==>_ChangeDestopWallpaper

Look here E1M1, that api function only supports bitmaps. When you select a desktop image through the windows gui it creates a bmp copy of that image in the profile directory.
