It adds a DOM object to a marker which you can place an image in.
I am not sure exactely what you wanna do. In the past I need an marker with number on it (to display how many elements each place has). I released it as an open source code and you can find it http://zeetha.com/open/iconsharp.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
