title: Image gradient overly
body: <p>I have seen News Republic android app. it is really awesome application. as per my view, the developer team have applied unique gradient overlay in their application and that gives nice image output.
   here is a screenshot for the imageView before image got loaded:
       <a href="https://i.stack.imgur.com/Ijgxq.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/Ijgxq.png" alt="enter image description here"></a> </p>
  
  <p>and this after:
  <a href="https://i.stack.imgur.com/H2QxJ.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/H2QxJ.png" alt="enter image description here"></a></p>
