title: Constraining image height with bootstrap responsive image?
body: <p>Working on a site using bootstrap, in the portfolio section, the images of projects are responsive with :</p>
  
  <pre><code>'class' =&gt; 'img-responsive'
  </code></pre>
  
  <p>It works great for landscape images, the portrait images are blown up to fit width wise, but are too tall, is there a way to check for a portrait orientated image and just apply a fixed height of 600px for it?</p>
