Highlighting a feature on a centered querymap map?

Hey everybody,
I'm having two problems with a modified querymap I'm working with. In
an attempt to recenter to the queried feature, I followed Steve Lime's
advice in a past listserv post, which was:
Just centering is easy. In you're query template you might have
something like:
<!-- the image -->
<img src="/cgi-bin/mapserv?map=[map]&mapxy=[shpmidx]+[shpmidy]
&scale=250000[get_layers]&mode=map">
The result of this is almost exactly what I was looking for, except for
two things.
1. The querymap map size takes the main map's size, instead of the
smaller size I put in the QUERYMAP part of the .map file (see below).
How can I regain access to my original querymap specifications?
2. The other thing I'd like to have is my selected polygon hilite. Like
my first question, the hilite feature only works when I don't change the
img src tag. Is there a way I can have my cake and eat it too?
Thanks for helping,
~Becky
