Oh man, I don't know if I explained this well enough.

The stuff on terraserver-usa.com (as opposed to terraserver.com -- same
company, different website), including the images I fetched, are
all free through the web interface.  Try it out with the browser of your
choice; you'll see it all just by clicking on links.  Before,
terraserer-usa only had one dataset of free aerial images.  Now they
have a second, which improves coverage in U.S. urban areas.

Heh.  But again, I wasn't fishing for available images by tweaking the
URL Dave uses in TaxiDraw.  These images are available normally,
through normal use.  There was no detective work on my part in finding
the images, because they provide them to you with nice informative links.
The only thing I did was figure out how to get fetch.cpp to draw from
the new dataset instead of the old one-- something that would have been
trivial for anyone who knows c++ (but I don't).
