title: Pass Base64 jpeg image to og:image
body: <p>I have image that is being generated in runtime on my website and I display it in html using </p>
  
  <pre><code>&lt;img src="data:image/jpeg;base64,&lt;!-- base64 data --&gt;" /&gt;
  </code></pre>
  
  <p>Now, I want for Facebook to fetch this image, but if I do the same for og:image meta tag, facebook debugger gives me an error. Any solution?</p>
  
  <pre><code>&lt;meta property='og:image' content='data:image/jpeg;base64,&lt;!-- base64 data --&gt;'/&gt;
  </code></pre>
  
  <p>Of course, I would like to avoid permanent saving of files since they are always different and it would get too crowded very quickly</p>
