Custom Markers from Image cck field

I was wondering if there are options to create dynamic markers by specifying icon path, size etc
as a parameter in settings when calling the gmap api theme('gmap', array('#settings' => $map_array1));

In that way, a user could use the content of a cck image field.

$map_array1 = array(
'id' => "mymap", // id attribute for the map
'width' => $width, // map width in pixels or %
'height' => $height, // map height in pixels
'zoom' => $xzoom, // zoom level
'maptype' => "Map", // baselayer type
'controltype' => "Small", // size of map controls
'markers' => array(),
);

$map_array1['markers'][] =array(
'text' => '

',
'latitude' => 39,
'longitude' => 22,

'icon' => array(
'image'=> 'http://www.google.com/intl/en_us/mapfiles/ms/micons/blue-dot.png',
'shadow'=> 'http://chart.apis.google.com/chart?chst=d_map_pin_shadow',
'iconSize'=> '12, 20',
'shadowSize'=> '22, 20',
)
);

theme('gmap', array('#settings' => $map_array1));
