When adding articles to K2, they aren't showing the images.
Here is an article that I have saved as html from the clients site.
www.osdcs.com/fb-page/8302-exclusive-guidebook-to-false-confessions-key-document-john-yoo-used-to-draft-torture-memo-released.htm
the result is the same. Facebook doesn't show the article image when entering the URL as the message.
It seems that the elements that contain the images are hidden for some reason in Firebug.

Any ideas how to get arount this as the client has like 60,000 articles.

Did you upload the image using the image tab?
