I want to make a slideshow of 100 or so photos each of which is about 3MB in JPEG format. That makes for a pretty unwieldy (SLOW) slideshow! In the Windows version of PP, there is a way to compress all the photos after they're on the slides so that a 200MB show ends up at about 15MB!! I can't find the same process available in PP for Mac. Anyone know how to do it? Thanks!
