when i press the play button (i-life5), it goes straight to the slide show. When i click on the settings icon it gives me options to repeat, scale to fit, ken burnsm titles, ratings, and show controls, as well as an option to fit the slideshow to the music, but no option for random slideshows. I know it has to be here, but i can't find it....thanks
Click the arrow button at the bottom left of the iPhoto window. Not the button that says slideshow, the one right next to the plus button. That will give you the option to shuffle the photos. This is of course in iPhoto 5.
FWIW, if anyone with a pre-iPhoto 5 version reads this thread, the feature is also available in versions as early as iPhoto 2. In iPhoto 2, you can get to it by clicking slideshow in the bottom toolbar (but not by clicking on the arrow next to the plus). For iPhoto2, the option is near the top of the ensuing requester....
