"IMAGEURL "/tmp/" means that the saveWebImage() method will create image 
paths starting with this value. If you get a broken image that must be 
because the http://your.host.name/tmp/... URL path does not point to the 
location of your images as it should.

To fix this, make sure your Apache (or Web Server, whatever it is), has 
an alias (or symbolic link) pointing the http://your.host.name/tmp/ URL 
to the /ms4w/tmp/ms_tmp/ directory.
