title: FB sharer not showing an image
body: <p>Ihave a sharer FB popup window on my site. It worked, but for some time it doesn't show an image of a page. My code of the link:</p>
  
  <pre><code>&lt;a title="Opublikuj na Facebook" onclick="window.open('http://www.facebook.com/sharer.php?s=100&amp;amp;p[summary]=Sebastian+%C5%9Awiderski%2C+by%C5%82y+reprezentant+Polski+i+trener+Zaksy+K%C4%99dzierzyn+Ko%C5%BAle%2C+potwierdzi%C5%82+sw%C3%B3j+udzia%C5%82+w+meczu+gwiazd+dla+hospicjum.+Pojawi+si%C4%99+r%C3%B3wnie%C5%BC+Piotr+Makowski%2C+szkoleniowiec+reprezentacji...&amp;amp;p[title]=Kolejne+gwiazdy+potwierdzaj%C4%85+sw%C3%B3j+udzia%C5%82+w+turnieju+dla+hospicjum&amp;amp;p[url]=http%3A%2F%2Fsalps.szczecin.pl%2Findex.php%3Fcontent%3Dnews%26view%3D285937&amp;amp;p[images][0]=http%3A%2F%2Fsalps.szczecin.pl%2Fzdjecianewsow%2F285937_1.jpg', 'sharer', 'toolbar=0,status=0,width=548,height=325');" href="javascript: void(0)"&gt;&lt;img src="maingraphics/f_logo.png" alt="Facebook logo"&gt;&lt;/a&gt;
  </code></pre>
  
  <p>What can cause, that image is not loaded? It is public and anyone can access it.
  Any ideas?</p>
