title: Captcha Image not visible on Google Chrome
body: <p>I have implemented a simple captcha on my app as described on this <a href="http://www.stefanprodan.com/2012/01/user-friendly-captcha-for-asp-net-mvc/" rel="nofollow noreferrer">blog post</a>. No change exactly the same code.</p>
  
  <p>Everything works very nice with Internet Explorer 11 as well as with Firefox 35.0.1. </p>

  <p>However something bad happens with Chrome 40 as the Captcha image is not visible at all.</p>

  <p>I have tried to check the rendered code with the developer tool and I can even see the image by hovering on the image source attribute.</p>

  <p>Any suggestion on changing the code to make it working on Chrome too?</p>
  
  <p><strong>EDIT</strong>: I have solved the problem by removing the Bootstrap CSS <code>class="img-responsive"</code> from the markup code. However I would like to understand the reasons of this behaviour.</p>
