Note: Flickr recently went through a massive server transition, and portions of the service are still being worked on. Among the problems is that mosaic thumbnails on Collections are not visible, which means my primary page here for showing groupings by year are missing those thumbnails. The links do work—only the thumbnails are missing, so you can still navigate into a year to view those photos.
Update to this story, Apple (to my immense shock) refunded all five books! The option given in response is to, within 40 days, requeue the order since they keep submitted PDFs for that amount of time, and have my CC be re-charged. But I only need one more book, not five, so I'm thinking I'll just upload a fresh order for one book through iPhoto.
