large scale image tiling

[Andrea Goethals]

Example map file showing tiled images:
(Note that I have 2 entries referring to aerial photos,
one for the index, one for the images so that people
can choose to draw or not draw the index. Also, for 
the aerial images I set a scale to start drawing them
so that our servers aren't slowed down by people trying
to draw the aerials when they're zoomed out far.)
