Map fails to display in interactive mode (&mode=browse). Help!

So I'm experimenting with MapServer on my notebook
with Windows XP SP2, Apache 2.0.54, and MapServer for
Windows (MS4W) 1.2.2.

My file placement scheme is fairly complex, because I
put map-related files (.MAP, .SHP, etc) and HTML files
on different folders. Here's the folders where I put
map-related files:
C:\mapfiles\mapfile\
C:\mapfiles\shp\
C:\mapfiles\font\
C:\mapfiles\simbol\

And here's the folders where I put HTML templates and
TEMP files:
C:\ms4w\Apache\htdocs\html\
C:\ms4w\Apache\htdocs\temp\
C:\ms4w\Apache\cgi-bin\ -=> where mapserv.exe
 resides


I do not use absolute folder hierarchy in my URL
references, though. Instead, I use relative folder
hierarchy. For example, here's how I write the URL on
my browser, to call a map file from the folder where
mapserv.exe resides (traversing from
C:\ms4w\Apache\cgi-bin\to C:\mapfiles\mapfile\):
http://localhost/cgi-bin/mapserv.exe?map=../../../mapfiles/mapfile/map01.map&layers=All&mode=map


And
 here's how I specify the SHP folders from my map
files.
  SHAPEPATH "../shp"
  FONTSET "../font/font.dat"
  SYMBOLSET "../simbol/simbol.sym"
  IMAGECOLOR 210 233 255  # biru muda

  WEB
     TEMPLATE
'../../ms4w/Apache/htdocs/html/map01_tmp1.html'
     IMAGEPATH '../../ms4w/Apache/htdocs/temp/'
     IMAGEURL '../../ms4w/Apache/htdocs/temp/'


So as you see above, I use relative folder hierarchy
to specify those folders (IMO it's a good practice in
linux environment).


So far, I have created various map files and I haven't
had any problems displaying maps (SHP layers) in
static mode (&mode=map).


Then I tried to use interactive 
mode (&mode=browse). I have created a map file for
that purpose, and I have made the necessary HTML
template file and the HTML legends file. I attached
those files with this mail:
- map file: map01.map
- HTML template: map01_tmp1.html
- HTML legends: map01_leg.html

First, I tested my map file in static mode, and the
maps are displayed correctly without problems.
However, when I try to call the map file in browse
mode, the map just failed to display. All I got is
just red "X" where the map should be displayed.

(I cannot attach the screenshots because they're
larger than 80k)

I have confirmed that it is not the problem with my
browser; I have tried another browser (Opera) and the
problem stays. Besides, non-MapServer web pages (like
Google, etc) display pictures with no problem.

And when I checked the TEMP folder
(C:\ms4w\Apache\htdocs\temp\), MapServer actually
CREATED all those temporary GIF files whenever I open
the map file using browser mode. In fact, when I view
the resulting HTML codes from my browser, the page
DOES refer to the temporary .GIF files being created
by MapServer. I attached the resulting HTML code as
well (03_the_resulting_html_code.txt).

Alas, the page just does not display those temporary
GIF files --it just displays all the red "X" marks.

So what's wrong here? Is it the fault of my browser?
But I have tried other browser and the problem stays. 

Or maybe because my complex folder scheme? Probably
because I use relative folder hierarcy to call the
necessary files? But all map files I have created have
no problems at all displaying the maps in static mode.

Or maybe there's a component I forgot to install?

Help!
