title: Images do not show up in build of App IONIC 2
body: <p>I am new to Ionic 2 and I am having some problems with images in my app.
  Searching online I understood that the images must be put in the /src/assets folder inside the app. (<em>correct?</em>)</p>
  
  <p>The images work fine using <code>ionic serve</code> and <code>ionic lab</code> commands but in the simulated devices or using Ionic View on an iPad they do not show up!</p>
  
  <p>I reference the images in the code with:</p>
  
  <pre><code>&lt;img src="../assets/img/ringing.png" class="circle_icons"&gt;
  </code></pre>
  
  <p>How can I solve this?</p>
  
  <p>(Down are some screenshot of the problem)</p>
