title: Hiding text that is not in its own tag, but not an image in the same parent tag
body: <p>I have the following HTML:</p>
  
  <pre><code>&lt;span class="wrapper"&gt;
    &lt;img src="..." /&gt;
    Some text!
  &lt;/span&gt;
  </code></pre>
  
  <p>How can I hide the text, but not the image, when the text doesn't have it's own tag?</p>
