Note:- Your desire wallpaper should be in same path when it was during you save the theme for example: In display properties, in desktop tab i browse wallpaper from \windows\web\wallpaper\NAME.jpg and i copied that wallpaper to \$OEM$\$$\web\wallpaper. i hope you can do that, i did this. if u r not satisfied. convay me i will give u a registery tweak, it will definately work but after doing from registry you will not been able to change your desktop wallpaper later until you delete that registry.
