title: how can I prevent facebook from cropping external link thumbnails?
body: <p>Consider the image shown here <a href="http://www.facebook.com/CT.dineto" rel="nofollow">http://www.facebook.com/CT.dineto</a> under the "Please peruse our New Testing Menu" shared link.</p>
  
  <p>The link points to this page:
  <a href="http://www.dine.to/article2.html" rel="nofollow">http://www.dine.to/article2.html</a> 
  the og meta tags in there seem  OK according to the Facebook debug tool.</p>
  
  <p>Notice the original  image is not square but 440x240px in size, but when shown on timeline as a thumbnail it gets cropped to a square and not just resized.</p>
  
  <p>So my question: is there a way to have the thumbnails be resized versions of the original image rather than cropped and squared?</p>
