Inserting a picture on PowerPoint slide is a frequent and commonplace task, and to you, this may look like a simple activity. But this simple task includes few options. You know that pictures located in any of your folders can be inserted on a slide. By default, PowerPoint retains no relation; even if you delete or move the original picture file you inserted, the copy on your slide will still be retained since PowerPoint saves the picture as a part of the file it creates. Yet, there are options within PowerPoint that let you maintain the relation between the original picture and the inserted picture. For example, if you make changes to your original picture, PowerPoint will update its copy on the slide!
