Hello Aphine, and welcome to Seven Forums.
Where do you have the wallpaper saved at that you are using?
If it was in say one of your administrator's account user folders before, then the other user would not have had permission to access it leaving them a blank wallpaper instead.
Try having it saved in a C:\Users\Public folder instead, and use that path in the tutorial.
Hope this helps,
Shawn
