when I post this URL http://charrette.callison.com/?p=686 in FB all I get is the logo thumbnail as a choice not the video thumbnail - am I doing something wrong ?
as mentioned in the faq, facebook caches previously shared/liked pages for a week or two. you can always make sure that everything is in order by taking a look at your page's source-code, or you can force a cache expiration by posting the link on the facebook debugger. i've already done the latter, so you should be able to see the image the next time you're posting the link on facebook!
I tried that - nothing is working
hm, can you make sure the mistake is not on your end (browser cache, facebook cache etc.) because that specific page is fully working
you could also try appending several /s or #s at the end of the url - or try some url shortener, but the facebook debugger alone should do it. i'll be glad to help once i know where to start!
