Hello, I added a facebook button to the site from my signature (bottom of the page). OK. The issue is that when a user clicks the button, facebook selects a wrong image. I setup <meta property="og:image" content="http://www.url"/> in the head of the page , but it still don't select this image. Any ideas ? Thanks.
I fixed the issue - the image must be at least 200x200px even if they say here http://developers.facebook.com/docs/reference/plugins/like/ as they should be 50x50px
