title: Twitter bootstrap: Centered Thumbnails
body: <p>I have a list of thumbnails. They have fixed size. I would like that the number of thumbnail in a row change with the width of the windows.</p>
  
  <p>That's easy with Twitter Bootstrap: <a href="http://jsfiddle.net/charlesbourasseau/5WvAL/" rel="nofollow">http://jsfiddle.net/charlesbourasseau/5WvAL/</a></p>
  
  <p>The problem is, when the screen can accept like 4.5 Thumbnail, they are all align to the left and I get a gap on the right.</p>
  
  <p>I would like to know if there is a possibility that the thumbnails stay centered, so the gap to the left and to the right, always stay the same...</p>
