Multiple marker icons, how to add to google mashup

Question

I have created a Google maps mashup, where with a bit of input, I have managed to have a sidebar that links to a video icon/marker that then opens up an info window showing virtual tours. I would, however, like to put different coloured marker icons on the map depending on the category that the video is in. This would be easy enough to do, but my page is made up of a mixture of J-Query and JavaScript all calling to the individual flash files. Could someone help me with the code for adding extra marker icons for different categories? Here is the code:

So, after the intial 'var camera;' point, there comes this:

function addMarker(point, title, video, details) { var marker = new GMarker(point, {title: title, icon:camera}); GEvent.addListener(marker, "click", function() { if (details) { marker.openInfoWindowTabsHtml([new GInfoWindowTab("Video", video), new GInfoWindowTab("More", details)]); } else { marker.openInfoWindowHtml(video); } }); Then further down, is the code for calling the individual marker image. I would like to add another image to this list - would I start out by calling the new object 'camera-red.image' or something similar?

function initialize() { if (GBrowserIsCompatible()) { map = new GMap2(document.getElementById("mapDiv")); map.setCenter(new GLatLng(51.52484592590448, -0.13345599174499512), 17); map.setUIToDefault();

var uclvtSatMapType = createUclVTSatMapType()
map.addMapType(uclvtSatMapType);
map.setMapType(uclvtSatMapType);

camera = new GIcon(G_DEFAULT_ICON);
camera.image = "ucl-video.png";
camera.iconSize         = new GSize(32,37);
camera.iconAnchor       = new GPoint(16,35);
camera.infoWindowAnchor = new GPoint(16,2);
addMarkersToMap();

} The actual map can be found here: link text

Thanks.
