title: Why suddenly minimum image size for og:image Facebook OG
body: <p>The <a href="https://developers.facebook.com/docs/sharing/best-practices#images" rel="nofollow">developer page of Facebook</a> tells me:</p>
  
  <blockquote>
    <p>If your image is smaller than 600 x 315 px, it will still display in
    the link page post, but the size will be much smaller.</p>
  </blockquote>
  
  <p>If I do this <a href="https://developers.facebook.com/tools/debug/og/object?q=http%3A%2F%2Fcaesarsbeauty.nl" rel="nofollow">FB Debug Fetch</a> my preferred og:image is not showing, Facebook tells me:</p>
  
  <blockquote>
    <p>og:image was not defined, could not be downloaded or was not big
    enough. Please define a chosen image using the og:image metatag, and
    use an image that's at least 200x200px and is accessible from
    Facebook.</p>
  </blockquote>
  
  <p>QS1) Why is there now suddenly a minimum size required?
  QS2) Why, if 200x200px is the minimum, is FB not having any trouble with my 140x140 image in this FB Debug Fetch? UPDATE: I just did the  fetch again and now suddenly I get the same warning here, so I quess only QS1 remains > or is Facebook just corrupt and not always giving the correct information?</p>
