Can I create my PDF file using an application other than iPhoto or Aperture?
We don’t officially support PDF files created in applications other than Apple iPhoto or Aperture. This is because the PDF standard is a wide ranging specification, and for the time being, we can only guarantee being able to support certain types of PDF files. However, you can design your book using another application (like InDesign or Quark), export out the book design as a PDF file, and then rasterize each page as a high-quality JPEG image (i.e. you would send us 1 JPEG image for each page of your PDF file). You can automate this rasterization of the PDF file using Photoshop or Acrobat Pro 7.0. In the future, we plan on expanding support for books designed via PDF files using applications other than Apple iPhoto or Aperture.
