How do I remove or replace my book's cover?
From version 1.9.22, open the book's page and find the Covers card. Under the front or the back cover, press "Replace" to upload another picture, or "Remove" to take that cover off the book. A removed cover is not lost: a copy stays in the Cover Studio gallery (Covers in the sidebar), so you can put it back later. You can also make a new cover in the Covers card or in the Cover Studio.
