Setting Up Screen Savers
In the past, you needed a screen saver (a continually moving display) to protect your monitor from screen burn in. With new technology, those days are gone. Screen savers are more for entertainment than anything else. When you leave your computer idle for a specified wait time, a screen saver displays a continuous scene, such as an aquarium, until you move your mouse to stop it. If a security option is set in the Security & Privacy pane in System Preferences, your computer requires a password when you wake from a screen saver. You can select a slide show (New!) or screen saver (New!) from the ones provided with OS X, such as Sliding panels or Photo Wall, or select a source, such as National Geographic (New!) or a folder on your computer with pictures (all saved in the same format). With iTunes Artwork, you can turn screen saver into a jukebox; just click an album. With iPhoto, you can use onscreen controls to pause or flip through photos in an album.
