Adding Audio and Sound Folders to iMovie

Nice Tutorial over at Macworld: How to Add (and Remove) audio and sound folders to iMovie
iMovie 6’s Media tab is a very handy tool for adding audio and visual effects to your movie projects—assuming your media are in a folder that’s listed in either the Audio or Photos tab within the Media section. But what if they’re not? For instance, I will sometimes use a desktop picture as the background behind some scrolling text. I can drag the image to be used into iMovie each time, of course, but things would be much simpler if I could just make my user’s Pictures folder available on the Photos tab in the Media tool.
