Steps to resize PowerPoint images with Macro

When you're going to upload your images to a presentation, you need to make them look balanced and organized. Moreover, it also makes a difference when it comes to PowerPoint presentation file size. Uploading nearly 15 images without resizing will result in a much larger PowerPoint presentation than if you had resized the images.
