---------------

      Now, we want this logo to be seen on every page up in the upper
      left-hand corner, so put a reference to it in the
      *standard_html_header* method::

        <html>
          <body>
            <dtml-var logo>

         An extra note here would be in order about "Acquisition".
         This file "logo" is in the same directory or it can be in any parent directory. however with the promotion of
         using folders to organize files, explaination of how an IMG link would go to a child folder would be most
         helpfull.

         Suppose you have a folder at root level called "images" where image objects are, and you have and image with
         name "myImage" ..then it would be like this:
         <img src="images/myImage"  
         ...  so its folder + / + image object name

         I would assume that standard ".." notation for moving up in the directory
         structure still applies?  (in other words, if "logo" is in the root directory,
         and you are in another directory within root, then you would access it with
         <img src="../logo">)

         That doesn't work for me, I have an image in Sales, so I write <dtml-var Sales/float.jpg> and I just get an
         error, <img src=Sales/float.jpg> works, so what's wrong?

         I tried it again with renaming it to float and it still doesn't work, it works though if it is in the root
         directory with the standardhtmlheader file, but why can't it be in any other directory to work?

         Is standard_html_header a method or an object? Both? What kind of object would it be? I'm having trouble
         keeping these concepts clear.

         Aug 2: this is a dtml-question, post to zope@zope.org ("Sales['float.jpg']" or so)
         Sep 9: its a method. Methods dont have properties (like "title"), they aquire them from their callers.

         standard_html_header is an object with a "meta_type" "DTML Method" in the zope object database, pre-built-in
         zopes root folder. It contains executable dtml.
