The Media Browser is a central repository of media content that you can use in your presentations. It has six tabs that we have covered extensively: Photos, Audio, Movies, Clip Art, Symbols, and Shapes. These six tabs are primarily of two types: Tabs that catalog content in your Mac OS X special collections and Tabs that catalog Microsoft Office assets. Although the first category of tabs may appear restricted to the Mac OS X special collections, they can be tweaked to show content from any other folder on your computer. In fact you can add more folders to the Folder / Browser pane.
