city-locatting OK... next step! =)

To have a browsable map you MUST set imgext to be the extent of the
displayed map. The way you've got it set up now doesn't give you that
information. MapServer certainly calculates it in building the image but 
since your just retrieving the image there's no way to get it back to
you since you're not using templates. 

The solution is to calculate the extent in the client using a bit of javascript.
This is not hard. Then extent in hand you can use the image in a normal
mapserver form interface. Here's an example that does just that.

   Hi...
   OK, I've successfully used the [shpmidx|y] 
thing... But now, how can I use that to continue to
browse trough the map?
   Why won't something like
"???/mapserv?map=<?>&mapxy=-43+-20&scale=4&img.x=200&img.y=400"
work? Isn't defining a mapxy/scale pair the same as
defining a mapext? they should be equivalent!

(I'm almost understanding this thing. I hope I can
contribute to the documentation, because this program
rocks! :)   )
