Some time ago, I put a PowerPoint presentation together that included quite a number of Hi-Res photos. What I would now like to do is re-save those photos at a lower resolution to reduce the size of the file (around 318 megs at present). Is there some way to take a photo back out of a PowerPoint presenttation to edit it? At the moment I'm not having much luck. Wanna kill these ads? We can help!
