My epub passes all preflight checks. It fails with:
Your EPUB failed to validate for the following reason(s): * Contains invalid images.
All my images are in OEBPS/images, they are pngs, they are referenced by OEBPS/content.opf as being in images, and they're all there with full permissions. Are there any specifications that lulu has? Any more informative logging than "Contains invalid images"?
