Still on Example 1.9 --same here!

Hi, I just replied to Lawal's post and that reply should answer your issues as
well.  In your case, it looks like you installed the tutorial directly under
"/ms4w/Apache/htdocs"--that's fine but you're missing an opportunity to learn
more about Apache. ;)

Anyway, I see that you created a temp directory under tutorial but you're
pointing your IMAGEURL to "/tmp/"...  It should point to "/tutorial/tmp/".
This is really a web server issue--MapServer, when processing your mapfile,
uses local paths (that's why you have SHAPEPATH, IMAGEPATH, and all other
PATHs pointing to your local directories).  However, after MapServer finishes
processing the mapfile, the output images need to be referenced in web server
terms--the resulting HTML file that the browser reads has to reference the
location of your images in web server terms, not as local paths.  You need to
understand what your web root directory is and what an alias (or virtual
directory) is as they become important for referencing MapServer generated
images.  So, IMAGEURL is really the web server alias for your IMAGEPATH and
relative to your web root directory (which is "/ms4w/Apache/htdocs"), it is
under "/tutorial/tmp/".

This isn't an issue when using "mode=map" and when you're not using WMS or WFS
layers.  When you set "mode=map" you're telling MapServer to stream the image
directly to the browser and forego writing images to a tmp directory.  This
is also why you didn't have an issue with the images until now (when you use
"mode=browse").

I hope that clarify things up a little... (not quite like butter ;)
