Are these book finished? If so then save them as PDF files. There are two types of PDF files created: 1 - just begin to print the book and use the Save as PDF option. 2 - Hold down the Option key and click on the Buy Book button. This will create a PDF file with a page that's sized for the dust jacket, approx 32.8" wide, 8.9" high. There is a service that will print and bind books from the iPhoto and Photos PDF files, PrestoPhoto. I don't know if they've printed from the pdf file that includes the wide dust jacket page, but you can contact them and ask. lf not, dust jackets could be printed at a local printer on glossy paper if needed.
Unless Apple comes out with a new Photos version that won't allow creating PDF files for existing books, we should be able to continue to create PDF files of existing books.
I've been experimenting with the new print options and have found the following:
Mimeo:
Books: 6 sizes/styles
54 themes (25 in Photos 4) - 1,2,3,4,5,6,12,20 & 30 pics/page
100s of layouts - resize and relocate photos, change background color, add text
boxes to any page.
Calendars 14 themes (25 in Photos)
1-5 photos per page
photos and text in date boxes.
Cards: 4 styles/styles
38 themes - flat and folded
Motif:
Books 4 sizes/styles
7 themes - 1 thru 9 photos/page - 100s of layouts - change bg color -
Shutterfly:
Books 10 sizes/styles
15 themes
3 layouts - 1-12 photos/page
100s of layouts - some layouts with text. Need to sign to website in order to get all
of the available themes and layouts.
Gifts for Pet Lovers, Device Cases, Cards.
mpix: Prints, framed prints, canvas prints, metal prints, wood prints, acrylic prints
Panoramic books: 5 sizes, 2 cover choices, numerous layouts, create online thru
Photos. Very difficult to navigate.
WHITEWALL: Prints, framed prints, mounted prints.
WIX Photo Albums: 3 styles Online publishing of photo album.
FUJIFILM: Prints, Wall Art, Mugs & Drink ware, Home & Office, Large Format Prints,
So far, in my opinion, the best choice is Mimeo. It has the most versatile and user configurable books available. Even though Mimeo has their own website for creating books it works thru Photos rather seamlessly. It does have a steeper learning curve that iPhoto books had but is much more powerful, i.e. you can resize photos on a page and relocate, add text boxes to any page, etc.
Next, would be Motif, Shutterfly and mpix. Shutterfly and mpix would be the last on the list. Shutterfly required going online and working there, albeit thru Photos, and mpix was extremely difficult to navigate through and I was unable in the short time I worked with it to get a book started with my own photos.
So if you want to have the books printed by Apple you have a deadline to meet. Otherwise there are a couple of new reasonable options available.
