 }
function showPosition(position)
 {
 var latlon=position.coords.latitude+","+position.coords.longitude;
 var img_url="http://maps.googleapis.com/maps/api/staticmap"
 +latlon+"&zoom=14&size=400x300&sensor=false";
 document.getElementById("mapholder").innerHTML="<img src='"+img_url+"' />";
 }

  {
  case error.PERMISSION_DENIED:
   x.innerHTML="User denied the request for Geolocation."
