Re: marker div by id ?

I don't believe that the images associated with a marker are contained
in a <div>.

There is an undocumented API call that sets the zindex of a marker
marker.setZindex()
Which applies the specified style.zIndex setting separately to each of
the images in the marker.

When you perform a map.addOverlay(marker) the zindex is initially
calculated like this

marker.setZindex(Math.round(marker.getLatitude()*-100000));
