I eventually had to do it all manually in iMovie which was tedious. That is to enter each ident number to every image. Unfortunately I was under a bit of a deadline for a disk. I shall now investigate further and try the iPhoto method, saving to iMovie, which then moves the final complete movie file to iDVD to burn the DVD, without menus as I don't want them! It's all a bit of a workaround but I want to use iMovie for my slideshow instead of just iPhoto/iDVD as I have been disappointed with using iPhoto on it's own in the past and I think iMovie gives a more professional look and has more design options.
