How do you add screensavers to a Nook?

To add screensavers to a Nook, you typically need to connect the device to a computer via USB. Once connected, locate the "screensavers" folder in the Nook's directory or create one if it doesn't exist. You can then copy your desired screensaver images (usually in JPEG format) into this folder. After safely ejecting the Nook, the new screensavers should appear in the device's settings.
