title: DFP non javascript version not counting impressions
body: <p>I'm having an issue with DFP where it is not counting the impressions or clicks of my ads when I use the non javascript version. The Javascript version works fine. I read something about having a pixel 1x1 but didn't quite get it.</p>
  
  <p>Here's an example of an ad that prints correctly but never increases the impressions counter in DFP:</p>
  
  <pre><code>&lt;a href="http://pubads.g.doubleclick.net/gampad/jump?co=1&amp;iu=/xxxxx/unit_001&amp;sz=300x250&amp;t=some%3Dthing&amp;c=%recipient.timestamp%"&gt;
    &lt;img src="http://pubads.g.doubleclick.net/gampad/ad?co=1&amp;iu=/xxxxx/unit_001&amp;sz=300x250&amp;t=some%3Dthing&amp;c=%recipient.timestamp%"&gt;
  &lt;/a&gt;
  </code></pre>
  
  <p>I appreciate any help. </p>
  
  <p>Thanks!</p>
