title: How choose image size for adding own Overlay in google map api?
body: <p>When i try adding my image in google map the image is distorted. Current image size is 5000x2475px. How fix this problem?</p>
  
  <p>Maybe it's due to the parameters swBound and neBound?</p>
  
  <p>Current image params:</p>
  
  <pre><code>var img = document.createElement('img');
          img.src = this.image_;
          img.style.width = '100%';
          img.style.height = '100%';
          div.appendChild(img);
  </code></pre>
  
  <p>Maybe exist tool for detect correct swBound and neBound</p>
