XF 2.0 Sharing Posts on Twitter with picture shown


I have a question, I want to make it possible sharing posts of my threads on Twitter, including pictures of this posts, like a smale preshow of the Foto next to the text.

How can i get this? Tweets with pictures are lot more interesting!

Thx for your help! Cheers :)
OK, thx, but then its just a general logo for all tweets, etc.

Would be nice, if you sheare an thread/post from Xen-Foro, if you could have a pre-view photo from this topic...
