Finally found the straight forward ans to this
http://groups.google.com/group/google-chart-api/web/chart-types-for-map-pins
Thiss should be right on the v3 docs pages for images right here
http://code.google.com/apis/maps/documentation/javascript/reference.html#MarkerImage
if any google ites are reading this should not have taken me weeks to
stumple across this
an simple hint link in the ref docs & I would seen the light w/o any
doc just a link on the
MarkerImage right beside the url:string would dot it
To get a standard map pin with a letter inside, use an URL like
http://chart.apis.google.com/chart?chst=d_map_pin_letter&chld=A|FF0000|000000
The chld URL argument contains several components separated by "|".
The meaning of each component is:
1. letter to put in the map pin, for example A, b, or 9. This must
be in UTF-8, and then URL-escaped, so, for example, to get a space you
must type +, to get a plus sign you must type %2B, to get љ you must
type %D1%99, and to get 駅 you must type %E9%A7%85.
2. pin fill color, as a 6-digit hexadecimal number, for example
000000 for black, FF0000 for red, FFFFFF for white, or FFFF00 for
yellow.
3. text color, also as a 6-digit hexadecimal number.
