1) It is necessary to create a special folder and save the picture (your wallpaper) to that folder. You may use “My pictures” folder, but do not forget to delete other files from it, otherwise they will be shown as a screensaver too.
2) Open the “Control Panel” by clicking on “Start”.
3) Next step depends on your Operation system. If you use XP, click Display Properties. If you use Vista, click Personalization icon.
4) Select the Screensaver tab, and select the screensaver you want to use from the drop-down menu. In our case it is called My Pictures Slideshow or Photos or it may have a name you gave to it.
5) After that click Settings and click OK to confirm your changes.
