I just gave a webinar on upgrading to PowerPoint 2013, explaining all the new features and how to use them. During the webinar, I discussed 2 features that I realized are so hard to find that I really should share them with everyone.
In PowerPoint 2010 and earlier, when you chose Insert > Clip Art, you could specify that you wanted only photographs. You did that in the Clip Art task pane from the Results Should Be drop-down list, as you see here.
