title: Twitter bootstrap image rotating (unwanted)
body: <p>I'm writing a project and I have 3 thumbnails per row.</p>
  
  <p>Each one has this code:</p>
  
  <pre><code>&lt;ul class="thumbnails"&gt;
          &lt;?php foreach($list_pjt as $progetto): ?&gt;
              &lt;?= ($row_close_after_three_thumbs == 0) ? '&lt;div class="row-fluid"&gt;' : '' ; ?&gt;
              &lt;li class="span4 pjt-thumb" &gt;
                &lt;div class="thumbnail alert-&lt;?= $status_bg ?&gt;"&gt;
                  &lt;?php
                      $img_thumb_pjt = ($progetto-&gt;img == '' || $progetto-&gt;img == '0') ? "img/site_basics/pjt_thumb.jpg" : "upload/$progetto-&gt;pjt_table/".$this-&gt;session-&gt;userdata('user_id')."/$progetto-&gt;img" ;
                  ?&gt;
                  &lt;img src="&lt;?= base_url($img_thumb_pjt) ?&gt;" alt="ALT NAME"&gt;
                  &lt;div class="caption text-center"&gt;
                    &lt;h5&gt;&lt;?= (strlen($progetto-&gt;pjt_name) &gt; 25) ? substr($progetto-&gt;pjt_name, 0, 25).'...' : $progetto-&gt;pjt_name ?&gt;&lt;/h5&gt;
                    &lt;p class="badge badge-inverse"&gt;&lt;small&gt;&lt;?= $type_name ?&gt;&lt;/small&gt;&lt;/p&gt;
  
                    &lt;p&gt;&lt;small&gt;&lt;?= $this-&gt;lang-&gt;line('profile_last_mod') ?&gt;:&lt;br&gt;&lt;?= timestamp_to_date($progetto-&gt;last_mod, $this-&gt;session-&gt;userdata('lang')) ?&gt;&lt;/small&gt;&lt;/p&gt;
                    &lt;p&gt;&lt;small&gt;&lt;i class="icon &lt;?= $status_icon ?&gt;"&gt;&lt;/i&gt; &lt;?= $status_txt ?&gt;&lt;/small&gt;&lt;/p&gt;
                  &lt;?php if($progetto-&gt;completato != 0): ?&gt;
                      &lt;p&gt;&lt;a href="&lt;?= base_url('project/showpjt/'.$progetto-&gt;id_pjt) ?&gt;" class="btn btn-&lt;?= $btn_color ?&gt; btn-block"&gt;&lt;?= $this-&gt;lang-&gt;line('profile_open') ?&gt;&lt;/a&gt;&lt;/p&gt;
                  &lt;?php else: ?&gt;
                      &lt;p&gt;&lt;a href="&lt;?= base_url('project/newpjt/'.$progetto-&gt;pjt_table.'/'.$progetto-&gt;id_acquisto) ?&gt;" class="btn btn-&lt;?= $btn_color ?&gt; btn-block"&gt;&lt;?= $this-&gt;lang-&gt;line('profile_edit') ?&gt;&lt;/a&gt;&lt;/p&gt;
                  &lt;?php endif; ?&gt;
  
                  &lt;/div&gt;
                &lt;/div&gt;
              &lt;/li&gt;
          &lt;?php endforeach; ?&gt;
      &lt;/ul&gt;

  <p>Some picture, per what I see the ones who are horizontally taken, show up fine (see screenshot on the right) others are rotating (screenshot image one)</p>
  
  <p>This is the screenshot: <a href="https://www.dropbox.com/s/frkx5tp4u3tf6wg/Screenshot%202013-10-03%2012.31.30.png" rel="nofollow">Result</a></p>
  
  <p>Any reason for this? How do I fix it?</p>
