How to create a slide show in Photos
I have started a slide show with a name and one slide. I am having difficulty adding selected photos from a specific Photos photo album.

Open the album with the selected photos, then drag the photos to the icon of your slideshow in the sidebar.
When you add the photos, they may get rearranged. arrange them, after you added them to the slideshow. Try to keep the slideshow short, otherwise it will be a lot of work to arrange the photos properly.
