I'm putting together a slideshow for a group of high school students who I recently chaperoned on a trip to Italy. Everyone gave me their digital files for me to out the show together. My question: the files vary in size (all jpeg) with some being quite large 5+megapixels to much smaller. Is it helpful to resize all of the files smaller for the slideshow? I'm worried that if I have a slideshow with 400+ images that the final .exe file will be huge. Thanks, Tom
