title: I want to show network images with different aspect ratio. | I am working on React Native
body: <p>I have to show a list of network Images having different aspect ratio.
  I have to maintain the aspect ratio of images with width = 100% of screen size.</p>
  
  <p><strong>sample example:</strong></p>
  
  <p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
  <div class="snippet-code">
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;ScrollView&gt;
    &lt;Image source={{/* network image url */}} style={{width:100%, height=?}} /&gt;
    &lt;Image source={{/* network image url */}} style={{width:100%, height=?}} /&gt;
    &lt;Image source={{/* network image url */}} style={{width:100%, height=?}} /&gt;
  &lt;/ScrollView&gt;</code></pre>
  </div>
  </div>
  </p>
  
  <p>I have to specify the height as per the official doc. But what is the best practice to set the height in this case?</p>
