Thanks. I never have heard of it before. I have not had any php
experience apart from what I learned here with pmwiki.

Okay. This was my first entry into google maps.

Sure. But there is a load function at the beginning of the file, and I
thought it mayb be used.

This is not apparent when reading Cookbook/GoogleMapAPI.
Or do you mean I should read the Google Map Documentation?
I will do so when I get around to it.
But I missed reading that a point or a line is necessary.
I assumed the map can just be shown without points or lines,
at whatever centered location and zoom level.
If this is not so I would really really like to have this feature,
and be able to set mapcenter lat and mapcenter long. coordinates
both inside the map markup and as possible default values,
so a map can be shown without any point or line being set.

Beg to differ. There is a load function in gmaJs.js.
And the html page google provides as a starter when you sign up for a
key has got  a load function. But great if we don't need one.

I used it to get the map centered at  alocation, without using a point:

  $HTMLHeaderFmt['GmapCenter'] = "
        <script type=\"text/javascript\">
        function load() {
          if (GBrowserIsCompatible()) {
       //     var map = new GMap2(document.getElementById(\"map\"));
            map.setCenter(new GLatLng($clat, $clon), $zoom);

The variables $clat and $clon (for center latitude, center longitude)
I added the same as
variables $width, $height, $zoom etc can be used. Definitely a hack of
the script, and I don't recommend it and rather see you adding
something like it to the script. And I did not like to use this load
function, as I had to do more modification to the skin template in
order to call it. But it was a way to get a result, in my rushed
enthusiasm! If there is a better way I am all for it.
