Google Maps API: Adding letters to my markers on my google map

Question

I'm trying to add a letter to my marker and then have multiple markers (14 to be accurate) with letters. l have so far done this without success. I'm a complete novice with code and google API.

Can you tell what code l need to add and where?

Below is my code:

<script src="http://maps.google.com/maps?file=api&amp;amp;v=2&amp;amp;key=....
  type="text/javascript"></script>
<script type="text/javascript">
//<![CDATA[
function load() {
  if (GBrowserIsCompatible()) {

    var map = new GMap2(document.getElementById("map"));
    map.addControl(new GMapTypeControl());
    map.addControl(new GLargeMapControl());
    map.addControl(new GOverviewMapControl());
    map.addControl(new GScaleControl());


    var bounds = map.getBounds();
    var southWest = bounds.getSouthWest();
    var northEast = bounds.getNorthEast();
    var lngSpan = northEast.lng() - southWest.lng();
    var latSpan = northEast.lat() - southWest.lat();
    for (var i = 0; i < 10; i++) {
    var point = new GLatLng(southWest.lat() + latSpan * Math.random(),
        southWest.lng() + lngSpan * Math.random());
    map.addOverlay(new GMarker(point));

    var point = new GLatLng(lat,ling);
    map.setCenter(point, 10);
    var marker = new GMarker(point);
    map.addOverlay(marker);

}

   GEvent.addListener(map, "moveend", function() {
   var center = map.getCenter();
   document.getElementById("message").innerHTML = center.toString();
   });



    map.setCenter(new GLatLng(lat,ling), 7);

  }
}

Answer 1

If you're trying to change the marker itself look at http://googlemapsmarkers.com - if you use their URL for your marker you can specify what the marker looks like:

Use the Charts API to generate markers:
