how to display Screen-overlay on Google maps Like Google Earth using KML

I want to display the screen overlay on Google maps like Google Earth using KML.

Below is the sample code for displaying the screen overlay in Google Earth using KML but i need to display the image in Google maps.

<pre lang="xml">&lt;ScreenOverlay&gt;
    &lt;name&gt;Key&lt;/name&gt;
    &lt;Icon&gt;
        &lt;href&gt;files/mykey.png&lt;/href&gt;
    &lt;/Icon&gt;
    &lt;overlayXY x=&quot;0&quot; y=&quot;0&quot; xunits=&quot;fraction&quot; yunits=&quot;fraction&quot;/&gt;
    &lt;screenXY x=&quot;25&quot; y=&quot;25&quot; xunits=&quot;pixels&quot; yunits=&quot;pixels&quot;/&gt;
    &lt;rotationXY x=&quot;0&quot; y=&quot;0&quot; xunits=&quot;fraction&quot; yunits=&quot;fraction&quot;/&gt;
    &lt;size x=&quot;0&quot; y=&quot;0&quot; xunits=&quot;fraction&quot; yunits=&quot;fraction&quot;/&gt;
&lt;/ScreenOverlay&gt;</pre>


and i have googled and find out from the below link. the &lt;screenoverlay&gt; important attributes &lt;overlayXY&gt;,&lt;screenXY&gt; and &lt;rotationXY&gt; tags will not support in google maps.
