Google Maps - Custom Markers

[oo.Berserker]

I have a Google map with the standard markers on a page, below is the code for the map (attachments are not working). Can anyone explain to me what and where I need to do to use a custom image for the marker please.

Thanks in advance.



function load()
{
//<![CDATA[

if (GBrowserIsCompatible()) {


// A function to create the marker and set up the event window
// Dont try to unroll this function. It has to be here for the function closure
// Each instance of the function preserves the contends of a different instance
// of the "marker" and "html" variables which will be needed later when the event triggers.
function createMarker(point,html) {
var marker = new GMarker(point);
GEvent.addListener(marker, "click", function() {
marker.openInfoWindowHtml(html);
});
return marker;
}

// Map controls
var map = new GMap2(document.getElementById("map"));
map.addControl(new GLargeMapControl());
map.addControl(new GMapTypeControl());
map.setCenter(new GLatLng(45.91867663909007, 6.9358062744140625),11);
