This hook allows you to replace the numbered cluster icons with your own in the Google Maps plugin. The default path is “plugins/business-directory-googlemaps/resources/marker-clusterer/markers/m”. This points to multiple files in that folder: m1.png, m2.png, m3.png, m4.png, and m5.png.
When this hook is used, you must have images for each of the 5 levels. These images do not include any numbers. The numbers are added automatically by Google Maps.
