I have the following jQuery code which adds map marker clusters:
markerCluster = new MarkerClusterer(map);
I\'m using markerCluster.addMa
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:
-images
-m1.png
-m2.png
-..etc other files from the directory
-SOME_FOLDER //can be lib, libraries, what have you
-markerclusterer.js
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);
