Actually I had this done before I saw yours. I just finished the editing today. I needed this for a very non-computer type that will be adding his own images. I might do more if there is any interest.
BTW I had trouble hearing your audio. I had to turn it up to the point I was afraid I'd get blasted if an unexpected sound came by. Is this just my setup?
I don't have PowerCMS so that field is wide open for you and neilo. :)
