CGI Mapserver: raw URL zooming manipulation

[Matthew Pettis]

Hi Rich,

Thanks... the same problem persists when i use 'mode=browse' and use the
resulting image...

What might be related is the 'img' cgi control... can someone explain this
to me?  i read the documentation, but i don't get it... it doesn't show what
value (if any)... here is the documentation entry:

IMG
>
> The name associated with the inline map image used to record user clicks.
> What actually is passed are two variables, img.x and img.y.
>
> For the CGI Applications this is an essential variable, see the examples
> for sample usage.

there is no indication what type of value should be associated with it (like
the other values in the reference indicate... like "ID [id-string]"), but it
says it is essential and see the examples (which examples, i don't
know...).  can someone explain further how this control is used in a get
statement issued to the mapserv binary?

thanks,
matt
