Question

If I paste the following URL into Facebook I can share an animated gif. It\'s not a movie and not flash, Facebook now supports gifs without those workarounds. I can click it

Answer 1

An important point which answers have missed, how to make GIF image (if clicked) redirects to the article which belongs to instead of the GIF link itself?

The important parts are:

Add two og:url tags. First one should be the same as og:image pointing to the GIF image URL. Second one should be the URL to the article.
