So I finally did create the rotating header that I threatened in this post.
I followed this tutorial, and used 4 headers that I had already created using Courtney's instructions HERE.
I actually created the 4 headers weeks ago (when we were still at the beach), but I hadn't been brave enough to attempt the rotating part until now.
It was so easy to do! The directions for the rotating headers (they call it a "Slideshow Header") were very clear and easy to follow!
