title: Insert an image in chrome extension
body: <p>I want to know how to insert an image in a Chrome extension. </p>
  
  <pre class="lang-html prettyprint-override"><code>&lt;img id="image" src="logo.png" /&gt;
  </code></pre>
  
  <p>I'm inserting that html tag correctly into a website, but naturally can't load that logo.png image. </p>
  
  <p>Any ideas on how to modify manifest.json?</p>
