How to ungroup photos in Vintage Prints Slideshow?
Is it possible to change the grouping of photos in an iPhoto or Photos "Vintage Prints" themed slideshow? I want to keep the photos in the same order I have them, but change which ones are grouped by twos onto one slide vs. only having one pic per slide. So frustrated! Help!!
