title: Pick images of root folder from sub-folder
body: <p>Let's say following is the directory structure of my website :
  <img src="https://i.stack.imgur.com/0ityY.png" alt="DIR STRUCTURE"></p>
  
  <p>Now in <code>index.html</code> I can simply refer images like:</p>
  
  <pre><code>&lt;img src="./images/logo.png"&gt;
  </code></pre>
  
  <p>But I want to refer the same image from <code>sub.html</code>. What should be the <code>src</code>?</p>
