As a test - I put 2 photos per well using 8 wells = 16 photos.
When I press the preview button I only view slide show 1-6 and not 7-12.
I thought the programme was meant to show all the photos in the wells to create a slide show.
If I enter 30 photographs to the slide show and try to edit the order they are presented -only 11 photos appear in the screen.
It's not the way I would do it if I used SlideShow. But I rather use iMovie HD6 and creates mine as movies then drop them into the iDVD Menu - not in any wells at all.
But if You click on (cmd+L) or go up to menu and down Project to Add SlideShow.
Now drop Your photos here in this big white area.
Does this works any better ?
