Your NOOK includes two sets of screensavers; authors (portraits of famous authors) and nature (pictures of nature). Your NOOK defaults to the authors' screensaver when it goes to sleep.
You can select your Screen Saver is the image your NOOK displays after it has been idle for the amount of time you configured as the screen timeout.
To change the screensaver on your NOOK, follow these steps:
1. On the Settings screen, tap Screen.
2. On the Screen Settings page, tap the Screensaver button. A dialog box opens, listing the screensavers available.
3. Tap the name of the screensaver or set of screensavers you want to use. The dialog box closes, and your selection takes effect right away. Remember, you won't see the screensaver until the next time your NOOK goes to sleep.
NOTE: You can add your own collection of screensavers. Each image in the collection should be a .GIF, .JPG, or .PNG file. Connect your NOOK to your personal computer, and using your computer's file navigation controls, (such as Finder on a Mac) open the screensavers folder on your NOOK. Create a folder for your images and give it a one-word title, such as Kids. Then drag the .GIF, .JPG, or .PNG files from your personal computer into the folder you created. To make your screensaver active, select it using the steps above.
