When you use image swapping you are accessing mapserver in "map" mode,
which means mapserver is only producing an image, no temporary image
is saved to the server (or the client, jBox in this case) and
mapserver is not template variable substitution for you. So you need
to make additional calls to mapserver for any other things you need,
like a reference  map, scalebar, etc. You also have to keep track of
your map extents yourself (you could make another request to mapserver
to do the calculations, but that would involve more overhead that it's
worth).
