Lights, Camera, Action: Slide Shows Using Photoshop
You can create a mock slide show presentation by opening multiple images in Photoshop and then pressing Control-Tab to rotate through the images. Plus, you can hold the Shift key and click on the Full Screen Mode icon near the bottom of your Toolbox to allow your images to fill the full screen (holding Shift will switch all of your open images to the Full Screen Mode at once). Press Tab to hide your palettes and you’re all set to give a slick presentation. To exit your mini-slide show, press Tab to see the Toolbox, and then Shift-click on the Standard Mode icon.
