I am running MS4W, it is working fine, I downloaded Mapserver tutorial and
passed through it till example1-9. I have the folowing problem:
when I type: http://localhost/cgi-bin/mapserv.exe?
map=c:\ms4w\tutorial\example1-9.map&mode=browse
I see only 1 map though I should see pursunat to template file 2 maps: one png
image is generate in map mode and the other in browse mode. Instead of second
map I see a blank square and inside it is wtritten: Submit query.
Can you guys help me?
Here is the map file:

<p>This dynamic map is being generated in "browse" mode. Click
on any point in the map and see what happens.</p>
<p>Both of these maps use the same mapfile definitions. The difference is
that the second map (the dynamically created one) relies on HTML form
for interactivity. If you look at how this page is linked from the
previous
page, you'll see that it isn't the same as the previous examples. This
page is what's called, in MapServer terms, an HTML template. You will
learn more about HTML templates in section 2.</p>
<hr>
<p>have a look at the "form" block within this page (right
click
on your browser and select "view source" or something
similar):</p>
<pre> <!-- START OF MAPSERVER FORM -->
<form name="mapserv" method="GET" action="/cgi-
bin/mapserv40">
<!-- HIDDEN MAPSERVER CGI VARIABLES -->
<input type="hidden" name="map"
value="[map]">
<input type="hidden" name="imgext"
value="[mapext]">
<input type="hidden" name="imgxy" value="199.5
149.5">
<input type="hidden" name="zoom"
value="1">
<input type="hidden" name="mode"
value="browse">
<div align="center">
<table border="1" cellpadding="0"
cellspacing="0">
<tr><td>
<!-- THE INTERACTIVE, DYNAMICALLY CREATED MAP --
<input type="image" name="img"
src="[ img ]" width="400"
height="300">
</td></tr>
</table>
</div>
</form></pre>
<p>This block executes the MapServer CGI program ("/cgi-
bin/mapserv40")
each time a user clicks on the map. The map is actually another form
"input",
represented here by the line:
<pre><input type="image" name="img"
src="[img]" width="400"
height="300"></pre>
The items in square brackets ([map], [mapext], and
[img])
are what's known as MapServer tags--these are MapServer CGI variables and
they get replaced by the MapServer CGI program when it reloads. The tag
[map] is a placeholder for the mapfile path so it's replaced
with
"[map]" when MapServer runs. The tag [mapext] is
replaced
with the current map extent, "[mapext]", and the
[img]
tag is replaced with the path to the image the MapServer CGI program
creates,
"[img]".</p>
<p>The hidden variable "mode" with the value "browse"
tells the CGI program that it needs to create and dump an image in the
"tmp" directory. This image is then referenced as
[img] and
this is what you see on your browser.</p>

<p>There's really only one thing that's been added to the mapfile:</p>
<p>TEMPLATE 'example1-9.html'<br>
This tells MapServer to use the page "example1-9.html" as a
template file. MapServer will process this file and replace the tags it
encounters before sending it to the web browser. This is how the next
two sections in this tutorial works.</p>
<hr>
<p>This marks the end of Section 1. I hope you leave this section with
enough
knowledge on how things are set in a MapServer MapFile. I can't stress
enough the importance of keeping the <a
href="http://mapserver.gis.umn.edu/doc40/cgi-reference.html">MapServer
MapFile Reference</a> open as you create your own mapfile and
application.
Without it, I wouldn't have gone very far with this tutorial.. For a
hierarchical
view of the mapfile objects and keywords, please have a look at the <a
href="http://vega.unm.edu/mapserver_workshop/reference/mapfile-reference-
table.html">reference
page</a> from Earth Data Analysis Center (EDAC) at the University of
New
Mexico.</p>

I have modified the httpd.conf in this way:
Alias /tutorial/ "/ms4w/tutorial/"
<Directory "/ms4w/tutorial/">
Options Indexes MultiViews
AllowOverride None
Order allow,deny
Allow from all
</Directory>
<Directory "/ms4w/tmp/">
Options Indexes MultiViews
AllowOverride None
Order allow,deny
Allow from all
</Directory>
I believe that i am missing something with WEB object(IMAGEURL)
Can you give me from what I have written a hint about what should I write at
IMAGEPATH and IMAGEURL?
Thanks
