Create an Instant Photo Slideshow with Quick Look
Quick Look is one of the many Mac OS X features that make my OS choice cemented, I use it so often that I simply can’t live without it, and here’s a tip that I’ve been using a lot lately.
If you want to create an instant slideshow of images, simply select multiple images in a Finder window, and then hit Command-Option-Y to launch them into a full screen Quick Look mode. Now just press play, sit back, and enjoy!
Alternatively, you can hit the Spacebar to quickly enter Quick Look, and then manually select the Full Screen button, but the keyboard shortcut is much faster method. This is a really underused feature of OS X and deserves to get some use by anyone who frequently browses through images or just wants to show off some pictures to another party without any desktop clutter or launching additional apps.
