I use a PowerPC Mac and cannot install Silverlight, so I will not be viewing any of his work on your site.
You might still be able to look at the photos at BTZS.org without the plug in.
Fred: Thanks for posting these images. I think an impartial observer might say with no disrespect to the late Mr. Davis that he continues to be best known, as you have stated, for his work in "education" in the broadest sense. Those who take the time to consider and use the BTZS system gain an appreciation of how Mr. Davis build upon the work of Anselm Adams, Minor White, Richard Zakia, and so many others so as to make the application of the Zone System more accessible and easy to use. I have heard and read that understanding the BTZS methods can be difficult, and almost inaccessible. With respect to those who make such comments, I can only ask that they consider reading Minor White's books on the modern application of the Zone System, and then take another look at BTZS. Adherents of any successful method as a means of achieving any defined goad tend to think that the method they use is "the best" way of succeeding. In such context, those who use the BTZS system might be excused for having a similar sense. Photographers taking the time to read Mr. Davis's book will certainly find that they have an appreciation of incident metering, and that such metering removes the need to apply the sometimes difficult concepts of zones when exposing one's negatives. In addition, reading Mr. Davis's DMax news letters adds an overall gloss to a system that has enabled many to reach their goal of making reproducible negatives that can print reliably on one's printing paper of choice. The fact that Mr. Davis's photos are not to be found in multiple collections at multiple libraries and museums does not diminish his contributions. I apologize for what must appear to some to be a panegyric.
