title: Picasso loading thumbnails of all phone photos
body: <p>I want to display all photos form my phone and display them in gridview using Picasso. The problem is I don't know how to implement this.</p>
  
  <p>Currentyly im using this to query all phone photos:</p>
  
  <pre><code>Cursor cursor;
      String[] columns = new String[] {
              MediaStore.Images.ImageColumns._ID,
              MediaStore.Images.ImageColumns.TITLE,
              MediaStore.Images.ImageColumns.DATA};
      cursor = cr.query(MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
              columns, null, null, null);
      int columnIndex = cursor.getColumnIndex(MediaStore.Images.Thumbnails._ID);
      int columnPath = cursor.getColumnIndex(MediaStore.Images.Thumbnails.DATA);
  </code></pre>
  
  <p>And MediaStore.Images.Thumbnails.getThumbnail to get thumbnail's bitmap to inject to ImageView.</p>
  
  <p>How could I implement it using Picasso?</p>
