Few people realize that PowerPoint provides a feature that enables you to automatically center a photo on a slide.
This tutorial works with PowerPoint 2007 and 2010. You can align not just images, but also other objects, such as shapes and SmartArt vertically in the middle, horizontally in the center or both at once.
To do this, select the object you want to center. Now click the Picture Tools tab that appears.
In the Arrange section on that tab, find the Align menu. It can align the image in several different ways for you. The menu is shown in the screenshot below.
For other types of objects, such as SmartArt, you can go into that object's contextual tab on the top that appears when you select it. For example, there's a SmartArt diagram that I want to align. I go to the Format tab for it, as shown below and use the Align menu. By default, only the little Align icon is shown in this tab, rather than a button with the entire word on it.
Now you'll never have an awkwardly offset image-only slide in your presentations when you use PowerPoint.
