Images for portfolio project

Hi beautiful people.
I am struggling to get my images next to each other. They tend to be stacked on top of each other and to the right of the screen.
I would like to have 6 images. Three rows consisting of two in each row.
Any help would be much appreciated.

  <div class="col-md-4">
    <img  src="http://andyflavoured.co.uk/wp-content/forum/uploads/2014/03/bbc-website-down-3.jpg" width="300px"/>
  </div>
  </div>

Please post a link to a live version of your project.

Olaa.

I managed to find an answer on one of the other thread. It was the wrong bootstrap running.
Gracias
