Is there a way to customize the standard cluster icon marker which GeoMashup uses to display nearby posts grouped in a certain area?

By default it's a red dot in V2, or a blue dot in V3. I nee to customize its appearance and replace it with a background/image?

I am not going to explain all the JS code, but did you tried to simply EDIT those images (leaving the same name/path) ?? if you want a BIGGER image , you will need to go to the JS code and change the values. – krembo99 Feb 27 '12 at 3:54
mmm if you're suggesting changing a bitmap image loaded locally by GeoMashup no that wouldn't work for the cluster marker because as I figured out later the cluster marker is not handled by GeoMashup directly; probably has to be filtered with json client side because it's loaded by Google itself from a GeoMashup javascript file; for now I hacked that GeoMashup JS file to alter size/color of the marker. If this is what you really intended well then it's what I ended up doing :) – unfulvio Feb 27 '12 at 15:06
yes, that is what i intended- in all my website i load GeoMashup LOCALLY. and change the values for the bitmap as well as the SIZE which is important . – krembo99 Feb 27 '12 at 22:26
yws, I do know one . It is one that I wrote myself. But I have never released it to the wild . But more and more people are asking for this, so If I will find time in the next few days, or even today, I will do so and will let you know somehow. – krembo99 Feb 29 '12 at 0:50
yep.. if you want I have a beta . send me a mail and I can send it for you to test .. – krembo99 Apr 14 '12 at 11:34
