Compressing Pictures in PowerPoint for Smaller File Sizes

PowerPoint files are often too big to upload to dropboxes.  However, the majority of the time this is because images have been inserted into PowerPoint and they have not been compressed for viewing on a screen.  PowerPoint has the ability to compress large image files within your presentations, resulting in smaller file sizes and faster general performance in presentations.  Follow these instructions to compress images in PowerPoint.  This will not affect how the presentation looks on screen.
