title: Show particular thumbnail on Facebook when sharing TUMBLR link
body: <p>I read thru this post (<a href="https://stackoverflow.com/questions/689295/how-to-show-particular-image-as-thumbnail-while-implementing-share-on-facebook">How to show particular image as thumbnail while implementing share on Facebook?</a>) but, I'm trying to figure out if it's possible to do this with a Tumblr link and no server space to use. My "og:image" (the main logo) is not 200x200 when Tumblr automatically resizes it to fit and I can't upload an image with a specific filename to Tumblr or tinypic, etc. as far as I know...</p>
  
  <p>Any suggestions for some sort of "hack" for this? Thanks!</p>
  
  <p>Oh and, here's my blog and the image I'd like to use...</p>
