Embed Gmaps view in theme template

I use a view with :
Style: GMaps Static Map
Row style: Static map node marker

Display type is page.
If I launch its URL, Gmaps static map appears correctly.

I would like to embed this map picture in a template.
I use API :
$myview->execute_display($myDisplayId, $myArgs);

Result is I obtain only list of fields and not picture.

How could I do this ?
