Imagine you have inserted a picture in PowerPoint 2013, and then applied various picture editing options to enhance its appearance. For example, we added a border, applied some Picture Effects, etc. And then you realize that you have a better picture, or your boss asked you to change the existing picture to another one, but with all the same effects! You would probably delete the original picture and start all over again, and yes, that is a long process! Or you can change any existing picture into another with just a couple of clicks — retaining all effects.
