title: HipChat URL image preview
body: <p>The Atlassian product HipChat has an inline-preview for websites build-in. However, ScreenShot share websites such as Gyazo are able to change the image given to HipChat.</p>
  
  <p>For example, the URL is something such as: gyazo.com/slqrFasd
  However, they pass the following to HipChat: i.gyazo.com/slqrFasd.png</p>
  
  <p>I'm trying to do the same for my own website, and pass the actual image to their inline preview. How would I be able to do this?</p>
