Solutions for many markers in the same coordinate, Google Map mashup

Solution

There are a few Javascript libraries that implement Clustering and are very easy to integrate into an existing mashup:

- MarkerClusterer - I used this for a mashup and found it easy to integrate, with a nice set of default icons.

- ClusterMarker - I haven't used this one, but it seems pretty functional.

Problem

I am making a mashup where thumbnails will be shown over a google map. The problem is that many thumbnails will share the same coordinate. So if I plot them like markers, they will be one on top of the other. Have you seen any creative solution for this problem? Thanks
