Bill - It seems to me that voice over for the video is the minimum needed. If possible, provide tool tip text for each of the image access points at the end. I'm not familiar with Toutube issues though. Just to make your life more interesting, I believe that 508 (US Federal IT accessibility standards) apply here.

All,
With my sincerest appreciation of your help given in advance, I am a bit uncertain about the accessibility of this Youtube video – aside from Youtube issues itself – and would truly value your feedback, suggestions comments and so on. My opinion is that key visuals must be audio described, perhaps in text as a caption.

Thanks!
