I spent about twenty minutes viewing this site. Although I do not teach art, my husband teaches art appreciation and art history online. There is a great collection of art at the Legion of Honor, especially the European Paints (Seurat, Monet, El Greco, Etc.). The paintings on permanent display as well as the current exhibit would enhance any art history course. It is such a wonderful way to visit an art musuem hundreds and thousands of miles away. It was a very easy site to navigate.
Since I was a first time user, I think students and faculty would find this site extremely easy to use.
