Thanks for your brilliant plugin.
It's great with Twitter but we're having some problems getting it to publish images from Facebook posts.
http://www.facebook.com/CitizensUK (it's the Valentine's Day post) - and here is the original post: http://www.citizensuk.org/2013/02/valentines-day-citysafe-launch-at-victoria-and-euston-stations/
The diagnostic messages I got (in order) for that day:
1.No Post images found so loading blank to keep Facebook happy
2.Post Images : http://www.citizensuk.org/wp-content/plugins/wordbooker/includes/wordbooker_blank.jpg
Thanks - hope to hear from you. I have other thumbnail plugins: default thumb plus.
