So I give up and go to dinner.  When I come back, it's displaying the
expected behavior (the proper image loads).  So I go ahead and put the
other banners in place. Guess what? I'm getting the same thing.  I've
tried killing the browsers cache, the Zope cache, etc, but no dice. 
Now, I know that with patience it will all sort itself out, but can
someone tell me why it's this way?
