We understand that formatting of image-focused books have often been overlooked by other programs, and we're committed to avoiding that oversight. While Atticus may not be the perfect solution for image-focused books just yet, there are some workarounds.
You can create a book entirely using full-page images, and include any necessary text within the images themselves. You will want to ensure that the artwork is appropriately sized for the trim size you will be using.
If you need guidance in determining the dimensions of images, we have a calculator in this tutorial: https://www.atticus.io/calculate-image-size-for-print-and-ebooks/
Atticus is also integrated with BookBrush, so you can use their program to create pre-sized images to use within Atticus. To learn how to best use the Book Brush - Atticus integration, I recommended taking a look at this tutorial: https://www.atticus.io/atticus-and-book-brush-integration/
