title: Facebook share doesn't show images
body: <p>I code a news PHP script. End of each news I have a Facebook share button. The problem is I can't display thumbnail images with Facebook share.</p>
  
  <p>I tried Meta OG</p>
  
  <pre><code>&lt;link rel="image_src" href="" /&gt; 
  </code></pre>
  
  <p>element without any success. Interesting thing is, some of the domains which is using my news PHP Script, has no problem with it but some has.</p>
  
  <p>Domain without any problems:</p>
  
  <ul>
  <li><a href="http://www.yenialanya.com/manset/vergi-denetmenine-itiraz.htm" rel="noreferrer">http://www.yenialanya.com/manset/vergi-denetmenine-itiraz.htm</a> (please check the bottom of the news)</li>
  </ul>
  
  <p>Domains with problems:</p>
  
  <ul>
  <li><a href="http://www.usakhabermerkezi.com/egitim-ogretim/usak-universitesi-rektorluk-secimleri-sonuclandi-iste-secim-sonuclari.htm" rel="noreferrer">http://www.usakhabermerkezi.com/egitim-ogretim/usak-universitesi-rektorluk-secimleri-sonuclandi-iste-secim-sonuclari.htm</a></li>
  <li><a href="http://www.demokrathaber.net/dunya/dunyanin-ekseni-kaydi.htm" rel="noreferrer">http://www.demokrathaber.net/dunya/dunyanin-ekseni-kaydi.htm</a></li>
  <li><a href="http://www.tebilisim.com/v4/siyaset/benzin-zamlardan-bizde-hosnut-degiliz.htm" rel="noreferrer">http://www.tebilisim.com/v4/siyaset/benzin-zamlardan-bizde-hosnut-degiliz.htm</a></li>
  </ul>
  
  <p>I also tried <code>addThis</code> and it didn't solve the problem.</p>
  
  <p>All of the domain names above are using the same system. I thought it might be because of the system so I tried clean HTML page:</p>
  
  <ul>
  <li><a href="http://www.phpsistem.com/fb/" rel="noreferrer">http://www.phpsistem.com/fb/</a></li>
  </ul>
  
  <p>As you can see in the last example, I used 2 different kind of sharing options. First with popup. I sent all parameters over URL but some domains display images, some don't. I also added <code>addThis</code> option.</p>
  
  <p>I also thought about <code>.htaccess</code> and cleaned everything in it since I thought <code>.htaccess</code> might block something. I took every step very carefully which I could think of.</p>
  
  <p>This issue started to be annoying, I would be glad if anyone could help me out.</p>
