Research shows that people pay more attention to images than to text, but sometimes you want people to focus on the text, not on an elaborate or complex photo.
A nice compromise is to use icons and they are VERY common on slides these days. PowerPoint 365 includes icons in its collection of images (choose Insert> Pictures> Stock Images and click the Icons tab), and you can find icons in lots of other places, as well.
One simple way to use an icon is to put it in place of a bullet point, as you can see here:








Choose this tree — it’s nice and simple. When you click it, it appears in the middle of the slide.
Delete the 3 wavy lines. Then delete the 3 green fills. You’ll be left with an image like this. Do you see how clean and clear it looks?
Press the Shift key and drag the top-right handle of the copy to enlarge it. You press the Shift key to keep the image from being distorted horizontally or vertically.
Here’s the slide after the animation has played. Do you like it? Try creating your own iconic graphics in this way.
