First of all, it is necessary to create a special folder with the pictures/photos which you want to see in your screensaver.

For XP:
- Click Start, then click Settings and go to Control Panel.
- When the Control Panel window opens, double-click on the Display icon. This brings up the Display Properties window.
- Select the Screensaver tab, and select the screensaver you want to use from the drop-down menu. In your case it is called My Picture Slideshow.

For Vista:
- Click Start and go to Control Panel.
- When the Control Panel window opens, double-click on the Personalization icon. This brings up the Personalization Properties window.
- Select the Screensaver tab, and select the screensaver you want to use from the drop-down menu. It is called Photos.

Next steps both for XP and Vista:
- To change the settings, click Settings.
- Once you have finished changing the settings, click OK.
