title: How to point on first content image when you share article on Facebook
body: <p>I have page <a href="http://www.aboutphuket.ru/Glavnaya/Putevoditel-po-stranam-yugo-vostochnoiy-%D0%90zii/Putevoditel-po-Taiylandu/Taiyskiiy-yazik/S-chego-nachat-izuchenie-taiyskogo-yazika.html" rel="nofollow">http://www.aboutphuket.ru/Glavnaya/Putevoditel-po-stranam-yugo-vostochnoiy-%D0%90zii/Putevoditel-po-Taiylandu/Taiyskiiy-yazik/S-chego-nachat-izuchenie-taiyskogo-yazika.html</a> ; when I try to share it on Facebook, I can't choose images from article, Facebook takes banners or any other pictures.</p>
  
  <p>I read here <a href="https://developers.facebook.com/docs/sharing/best-practices" rel="nofollow">https://developers.facebook.com/docs/sharing/best-practices</a> about this META tag:</p>
  
  <pre><code>&lt;meta property="og:image" content="http://graphics.myfavnews.com/images/logo-100x100.jpg" /&gt;
  </code></pre>
  
  <p>But how can I insert first image from article in this tag in my template?</p>
