I would like to be able to share a link from another website (eg. New York Times) as a blog post, and have a thumbnail appear, as well as the title and link to the article - the way it works on Facebook. I'm using Twenty Ten as a theme. I'm not self-hosting my blog, so I can't install plug-ins, I guess - but it there some way to activate this feature? Perhaps using a different theme? I've noticed the Snap Shot feature, which is nice, but I'd really like to have an article's thumbnail automatically appear in my blog post (without having to do all the work of grabbing a graphic and uploading it myself).
I apologize if this has been asked and dealt with - I searched but couldn't find an answer.
The blog I need help with is mzvetina.wordpress.com.
