How to place an image on radmap?

[Jimmy]

I have a image, I wish to place it  on radmap (The effect  which just like this url:
http://maps.google.com/maps/mapplets?moduleurl=http://code.google.com/apis/maps/documentation/mapplets/examples/groundoverlay-simple.xml
and the details on 
https://developers.google.com/maps/documentation/mapplets/overlays?hl=eng 
Ground Overlays

Polygons are useful overlays to represent arbitrarily-sized areas, but they cannot display images. If you have an image that you wish to place on a map, you can use a GGroundOverlay object. The constructor for a GGroundOverlay takes a URL of an image and the GLatLngBounds of the image as parameters.

The following example places an antique map of Newark, NJ on the map as an overlay:

var map = new GMap2(); 
map.setCenter(new GLatLng(40.740, -74.18), 12); 
// ground overlay 
  
var boundaries = new GLatLngBounds(new GLatLng(40.716216,-74.213393), new GLatLng(40.765641,-74.139235)); 
var oldmap = new GGroundOverlay("http://www.lib.utexas.edu/maps/historical/newark_nj_1922.jpg", boundaries); 
map.addOverlay(oldmap);

),

How can I do?

Hello Jimmy,

The RadMap control allows showing of several map providers one over another. I would like to recommend you to take a look into the following samples:

Also you may find our documentation topic helpful for achieving this:
