I have 89 slides in MS PowerPoint 2013. I added background photos to make the slides more interesting. The file size grew to 25MB. Now PPT 2013 is a little slow (sluggish). Is there some way to decrease the file size, and yet keep the same aesthetics (or better)? Or how can I improve system performance? (Hardware graphics acceleration is off.)
Dell Inspiron 1749 laptop with a first generation Core i5 (M520), 8GB RAM, and an SSD. Windows 7 Professional x 64 (clean install four months ago, and I keep my system clean). Thank you.
