title: Change image size via parent div
body: <p>I tried to do so but it didn't change the size:</p>
  <pre><code>&lt;div style=&quot;height:42px;width:42px&quot;&gt;
     &lt;img src=&quot;http://someimage.jpg&quot;&gt;
  &lt;/div&gt;
  </code></pre>
  <p>What will re-size it (I can't edit/access the img element itself)?</p>
  <p>Thanks in advance.</p>
