I read thru this post (How to show particular image as thumbnail while implementing share on Facebook?) 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...
Any suggestions for some sort of "hack" for this? Thanks!
Oh and, here's my blog and the image I'd like to use...

(the image uploaded to tumblr as a private post... I've done stuff like this successfully before for things like the background image, etc.)
