Photos missing from exported slideshow.
I have created a slide show (with music) in Photos - 136 pictures. It views fine when played in Photos. However, most of the photos are missing - just a white screen - when exported to create an m4v file. The music is all there. I can't seem to find a similar situations discussed anywhere.
