I posted this in the app section, but no one had advice so maybe people here do. I made an iPhoto book that I would like to print again. However, since then I have started using Aperture, and moved my files into the Aperture folder. Now the pictures in the iPhoto book look pretty pixelated, and if I try to open one it says file missing. Is there a way I can still use this book for printing, or do I have to start over from scratch? Thanks for any advice!
