More Adjustments: Remove Background
You can
use the Picture Tools to Remove the Background on an image.
This option is similar to Cropping an image. However, you can be much more precise where the crop marks, or nodes, are placed.
Usually this is a task that is performed with a photo editor such as PhotoShop. However, the Picture Tools in PowerPoint work rather well.
