There are lots of pictures here, but I have broken them
up into many pages, so even people with slow connections
should be able to use them. Each of the links below leads
to a page of thumbnails, which should load very quickly;
clicking on a thumbnail gets you a somewhat bigger picture
none of them larger than 480 pixels in the longest dimension.
Of course I considered doing a more elaborate presentation,
with more complete annotations, but I concluded that quick
was much better.
