Add custom image to Marker Cluster without overwriting markers

I have the following jQuery code which adds map marker clusters:

markerCluster = new MarkerClusterer(map);

I'm using
to add individual markers to clusters (full code block at the bottom of the page).

The problem I have is my clusters have no image attached by default.

I can do the following:

var options = 'an image path';
markerCluster = new MarkerClusterer(map,markers,options);

However as options is the third parameter, I effectively overwrite the second parameter. Is there a way to set an image to MarkerCluster without overwriting the markers?

(function () {
var address = response[key]["address"];
$.getJSON(''+response[key]["post_code"]+'&sensor=false', null, function (data) {
var p = data.results[0].geometry.location
var latlng = new google.maps.LatLng(, p.lng);
var Marker = new google.maps.Marker({
position: latlng,
map: map,
content: address
google.maps.event.addListener(Marker, 'click', function () {
infowindow.setContent(this.content);, this);

By default, MarkerClusterer looks for markers in the ../images folder (relative to the position of markerclusterer.js).

The easiest thing for you would be to get the image folder from the github, so the structure of your files is following:

  -..etc other files from the directory
-SOME_FOLDER //can be lib, libraries, what have you

Alternatively you can play with imagePath attribute of the options object, so you would have something like this:

var options = { imagePath: "PATH_TO_IMAGES_FOLDER/m" };
markerCluster = new MarkerClusterer(map, markers, options);
