Instant Slide Show
The Slide Show command in Mac OS X is a really cool way to look at photos.
Let’s say you’ve downloaded a bunch of images from you digital camera onto your Mac. Select some or all of the images, Control-click (or right-click if you have a two-button mouse) on any image and choose Slideshow from the contextual menus. (In case you didn’t know, Mac OS X is LOADED with contextual menus). Ta-da! A full-screen slide show, complete with smooth dissolve transitions, appears on your screen. To end the show, press the Escape (esc) key on your keyboard.

Use the context menu to make a slide show
