title: Is srcset required for displaying HQ retina images?
body: <p>Let's say that I have an image <code>600x300px</code>.</p>
  <p>I display it with this code:</p>
  <pre><code>&lt;img src=&quot;image600x300.jpg&quot; style=&quot;width: 300px;&quot; /&gt;
  </code></pre>
  <p>The actual size of the displayed image will be <code>300x150px</code>.</p>
  <p>A smart browser could use two pixels to render each pixel (i.e. retina image). But... they do it automatically?</p>
  <p><strong>Do you get an improved result in the quality of the rendered image if you add <code>srcset</code> with the exact same image?</strong></p>
  <pre><code>&lt;img src=&quot;image600x300.jpg&quot; srcset=&quot;image600x300.jpg 2x&quot; style=&quot;width: 300px;&quot; /&gt;
  </code></pre>
