title: Icons don't show for Google Chrome Extensions
body: <p>I'm trying to code a simple Google Chrome Extension. Everything is alright apart from my icons.</p>
  <p>Below is my json file:</p>
  <pre class="lang-json prettyprint-override"><code>{
      &quot;name&quot;: &quot;Wikipedia Quick Search&quot;,
      &quot;version&quot;: &quot;1.0&quot;,
      &quot;description&quot;: &quot;Easily access Wikipedia from your page&quot;,
      &quot;manifest_version&quot;: 2,
      &quot;icons&quot;: {
          &quot;16&quot;: &quot;search16.png&quot;,
          &quot;32&quot;: &quot;search32.png&quot;,
          &quot;48&quot;: &quot;search48.png&quot;,
          &quot;128&quot;: &quot;search128.png&quot;
      },
      &quot;browser_action&quot;: {
          &quot;default_icon&quot;: &quot;search16.png&quot;,
          &quot;default_popup&quot;: &quot;popup.html&quot;,
          &quot;default_title&quot;: &quot;Quick Search&quot;
      },
      &quot;permissions&quot;: [&quot;activeTab&quot;]
  }
  </code></pre>
  <p>The icon names are all correct and scaled accordingly to the size requirements, but in chrome://extensions, the icons don't show up.</p>
