title: How to remove border from google map infobox?
body: <p>I have tried with several guides and stackoverflow questions to find out a solution for remove the extra space from info windows. My map looks like below. Help me to get rid of this. I just need to show the image with a small border on the map.</p>
  
  <p><img src="https://i.stack.imgur.com/KTG6f.png" alt="enter image description here"></p>
  
  <hr>
  
  <p>Here is the js for adding those info windows.</p>
  
  <pre><code>function addBasicInfoWindow(map, marker, contentStr) {
      var infoWindowOptions = {
              content: contentStr,
              pixelOffset: new google.maps.Size(0, 15),
              disableAutoPan: false,
              zIndex: 50,
          };
      try {
          basicInfowindow = new google.maps.InfoWindow(infoWindowOptions);
          basicInfowindow.open(map,marker);
      } catch (ex) {
          alert(ex);
      }
  }
  </code></pre>
  
  <p>tried with <code>closeBoxMargin: "10px 20px 2px 2px",
          closeBoxURL: "http://www.google.com/intl/en_us/mapfiles/close.gif",</code> but not working for me.</p>
  
  <p>Thanks in advance.</p>
