                </div>
              <script type="text/javascript"> function init_map(){var myOptions = {zoom:14,center:new google.maps.LatLng(55.7525021,37.6106717,19.71),mapTypeId: google.maps.MapTypeId.ROADMAP};map = new google.maps.Map(document.getElementById("gmap_canvas"), myOptions);marker = new google.maps.Marker({map: map,position: new google.maps.LatLng(55.7525021,37.6106717,19.71)});infowindow = new google.maps.InfoWindow({content:"<div><b>Россия</b><br/><img src='http://ihracat.info.tr/haberdata/tam/2013/38/71cb930c-8e8e-4754-92e3-70c171007ef4.jpg' style='width: 200px;'/><br/>Москва</div>" });google.maps.event.addListener(marker, "click", function(){infowindow.open(map,marker);});}google.maps.event.addDomListener(window, 'load', init_map);</script>
