PhotoBooth leparello binding
hello
unfortuanally IPhoto photobook have no leparello binding. Also in the new photo app there seems no possibility for leparello, whats a shame.
There is then only one option left - send feedback to Apple, and let them know. Use this link: Apple - iPhoto Mac - Feedback
And use a different printing service, while you are waiting. You could send the preview of your Photo Book to a different print service.
