  <p>According to Facebook's <a href="https://developers.facebook.com/docs/opengraph/" rel="nofollow noreferrer">Open Graph protocol documentation</a>, you may include multiple <code>og:image</code> meta properties to associate multiple images with your page:</p>
  
  <blockquote>
    <p><code>og:image</code> - An image URL which should
    represent your object within the
    graph. The image must be at least 50px
    by 50px and have a maximum aspect
    ratio of 3:1. We support PNG, JPEG and
    GIF formats. You may include multiple
    <code>og:image</code> tags to associate multiple
    images with your page.</p>
  </blockquote>
  
  <p>However, when I load my page in the <a href="https://developers.facebook.com/tools/lint" rel="nofollow noreferrer">URL Linter</a>, I get a warning:</p>
  
  <blockquote>
    <p>Duplicate tags:   You used "image" multiple times, but it should only appear once</p>
  </blockquote>
  
  <p>So which is it?</p>
  
  <p>Is there a better way to associate multiple thumbnail images with a page?</p>
