How do I add a logo, ISBN image, QR code, or other graphic?

Upload each asset to its matching slot under Images, then enable it in the advanced print settings. A logo can be placed on the back cover or spine. ISBN images and QR codes can be aligned near the bottom, while an Other image has top, middle, and bottom alignment choices.

Each enabled image includes vertical, horizontal, and size controls. Use transparent PNG files for logos when possible, leave room around QR codes and barcodes, and create a test render to confirm that small details remain sharp and scannable.
