How do I add an author photo or custom background graphic?

Open Images to upload or replace the Author Photo or Other image in your shared image library. The author-photo setting uses layouts designed for a portrait, while Other Image can place a custom graphic on the back cover.

For the custom graphic, choose an alignment and adjust its vertical position, horizontal position, and size. Use high-resolution artwork that you own, and check that it does not reduce the readability of the blurb or occupy the barcode area.
