Hi Manfred,

 I want the parcel link when you click it to load into the image page. like this site
http://www.houstonengineeringinc.com/mapmorph_demo/mapserv.html Here are the screen shots.  I dont want the query results to show up in a new page or the image parcel.  I want it to all be in the html page. 

Thanks,
Albert

sorry, I do not full understand your mail. Therefore I am not sure, what 
you have on the screen and what you want to have. The code examples that 
you gave: are these the template files which you use in your map file?

You wrote

"But I want to image of the parcel to load in the image map"

Do you mean you want a hilited parcel like in my example site? Or do you 
want something like an image map in html (that means: a map-tag with 
area definitions)?

For the hilited parcel you need a QUERYMAP object in your mapfile. For 
example:

QUERYMAP
   STATUS ON
   STYLE HILITE
   COLOR 0 255 255
END

Is your site available in internet, so me and others could have a look 
at it?

If not, can you give me your html files and map file and an example 
shapefile? I could put it on my webserver so we can look at it together 
and I can make fast modifications.

Or at least can you give a screenshot with your whole application 
including the result of a query?

Manfred
