title: og:image could not be downloaded because it exceeded the maximum allowed sized of 8Mb
body: <p>Building a website that requires sharing links with an image. Done this I don't know how often...but this time the Facebook Open Graph Debugger says:</p>
  
  <p>og:image {image url} could not be downloaded because it exceeded the maximum allowed sized of 8Mb</p>
  
  <p>But the image referenced is only 108KB? One other time it responded that my server might be too slow. But when I simply load up the image in a browser it's instantly there. Where should I be looking now?</p>
