The two black-and-white photos come from the Historic American Buildings Survey, which most likely doesn't have both buildings in one photo.  I have a present-day photo of the remains of Dow Hall, but I need to get my friend's approval to upload it under a Creative Commons license.  (This shouldn't be a problem, since I told him I wanted photos for Wikipedia.)  As far as actually formatting these photos is concerned, we could put in some sort of table after the two text sections of the article, and then everything should look nice.  (The "gallery" tag would work, too, but I'm not a big fan of it.)   (Elkspeak)
