Create a series of Keynote slides from a set of images: "I was surprised to find out this morning that there is an easy way to make a series of slides in Keynote from a group of images in the Finder.
From the Finder, simply highlight the images you want to import to Keynote and drag them to the Navigator window along the left edge of the presentation. (You may have to set your View mode to Navigator (e.g. Keynote » View » Navigator) first). Each image then appears centered within a separate slide. Voila!"
