I have an image-based pdf that contains front, front-inside, back-inside, back, and spine pages (in addition to the body pages). My spine page is the same height as the other cover pages but narrower. Is there a way to get this image onto the spine that shows when the book is freely rotated? So far I only see a plain white spine on the outside as well as the inside part of the spine that shows when the book is spread open.
(I mean to post this in the WordPress plug-in section!)
See binderTexture on the Cover properties tab.
Works beautifully, brilliant!
