title: Facebook share not showing the thumnail image
body: <p>Following is the code I am using to share my posts on Facebook. Everything is working properly but sometimes on some posts the thumbnail image is not showing.</p>
  
  <pre><code>&lt;?php
  $title=urlencode('Facebook Share Platform');
  $image=urlencode('imagepath');
  $summary=urlencode('Check This Out');
  $url=urlencode('http://apps.facebook.com/yourapplication');
  ?&gt;
  
  window.open('http://www.facebook.com/sharer.php?s=100&amp;p[title]=&lt;?php echo $title; ?&gt;&amp;p[summary]=&lt;?php echo $summary; ?&gt;&amp;p[url]=&lt;?php echo $url; ?&gt;&amp;p[images][0]=&lt;?php echo $imagepath; ?&gt;', 'sharer', 'toolbar=0,status=0,width=626,height=436');
  </code></pre>
  
  <p>I have checked the URLs and everything I could but couldn't figure out the problem. </p>
