Format in PowerPoint 365
When you insert pictures to your org chart (see how to create organization chart with picture) or other SmartArt chart with pictures, you don't need another program to prepare pictures. PowerPoint provides you a feature rich functionality for cropping, rotating, painting, and other formatting needs.
If you plan to create a presentation for your family, friends, or colleagues and have only photos, you don't need to spend hours on inserting and formatting pictures in PowerPoint. Use a relatively new feature Photo Albums that will automatically do all the work for you.
