title: How can I set height for Twitter bootstrap thumbnails?
body: <p>I’m having trouble setting up the Thumbnail module for my personal website. I use twitter bootstrap (3.0) for my project and I can’t finish setting up the Thumbnail module.</p>
  
  <p>The width is okay, but I can’t set the height of thumbnails (I can’t align all thumbnails as the same height).</p>
  
  <p><strong>How I can set one (standard) height for all the thumbnails and zoom/scale image to center so they can fill all space without stretching the image?</strong></p>
  
  <pre><code>&lt;div class="row"&gt;
  &lt;!-- Thumbnail 0 --&gt;
  &lt;div class="col-sm-6 col-md-3"&gt;
      &lt;a href="#" class="thumbnail"&gt;
          &lt;img src="img.png" alt="..."&gt;
      &lt;/a&gt;
      &lt;div class="caption"&gt;
          &lt;h4&gt;Arctic MX-2, 8g&lt;/h4&gt;
      &lt;/div&gt;
  &lt;/div&gt;&lt;!-- /thumbnail 0 --&gt;
  &lt;!-- Thumbnail 1 --&gt;
  &lt;div class="col-sm-6 col-md-3"&gt;
      &lt;a href="#" class="thumbnail"&gt;
          &lt;img src="blue.png" alt="..."&gt;
      &lt;/a&gt;
      &lt;div class="caption"&gt;
          &lt;h4&gt;Arctic MX-2, 8g&lt;/h4&gt;
      &lt;/div&gt;
  &lt;/div&gt;&lt;!-- /thumbnail 1 --&gt;
  &lt;/div&gt;&lt;!-- /thumbnail --&gt;
  </code></pre>
