Trying to buy an iPhoto book produced in iPhoto 9.6
When trying to buy the iPhoto book iPhoto tells me there are unused photo place holders and to either add a photo or change the layout. In iLife 09 it was possible to leave photo holders blank and iPhoto would ignore them. How can I do this in iPhoto 9.6
iMac (Retina 5K, 27-inch, Late 2014), OS X Yosemite (10.10.2)
