Here’s a short but useful iPhoto tip for your Thursday reading enjoyment. As you’re probably aware, there’s a Play button on the iPhoto toolbar. Click it, and the Slideshow dialog appears; set your preferred options and music then click Play, and you’ll enjoy a slideshow of your currently-selected iPhoto images.
But what if you don’t want to change the settings, and would rather just start the slideshow as quickly as possible? To do that, just hold the Option key before you press the Play button in the toolbar. Presto—an instant slideshow using your last-saved slideshow settings.
