title: Phonegap: get location tag from image in library/album
body: <p><code>navigator.camera.getPicture</code> is working reasonably well for me as is <code>navigator.geolocation.getCurrentPosition</code></p>
  
  <p>If my picture source type is in 0,2 though:</p>
  
  <pre><code>Camera.PictureSourceType = {
      PHOTOLIBRARY : 0,
      CAMERA : 1,
      SAVEDPHOTOALBUM : 2
  };
  </code></pre>
  
  <p>is there a ready way to retrieve the location data from these already saved images in phonegap?</p>
  
  <p>I'm calling like:</p>
  
  <pre><code>    params = {
          quality: 10
          sourceType: 0
          destinationType: Camera.DestinationType.FILE_URI
      }
      navigator.camera.getPicture @onPhotoDataSuccess, @onFail, params
  </code></pre>
  
  <p><code>onPhotoDataSuccess</code> is then a function of <code>imageData</code> which takes a <code>FILE_URI</code>.  Can I get the location tag from this, longitude and latitude?</p>
