change wallpaper or background in windows

[John]

ok iv done some looking around on the internet and i found that this code will only work with .bmp in xp, vista can use both .jpg and bmp

Code:

Copy      Help

str sPath  =  "C:\Users\Administrator\Pictures\Internet Explorer Wallpaper.bmp"

SystemParametersInfo SPI_SETDESKWALLPAPER 0 _s.expandpath(sPath) SPIF_UPDATEINIFILE|SPIF_SENDWININICHANGE

that seems to be what works best but in xp i cant use jpg how would i convert jpg or other image formats to bmp (with QM)?.
