So changing this line to

```haml
= link_to t('.facebook'), "http://www.facebook.com/sharer.php?s=100&p[title]=#{@project.name}&p[summary]=#{@project.headline}&p[url]=#{project_url}&p[images[0]=#{@project.display_image('project_thumb_facebook')}", class: 'button with-icon facebook', target: :blank
```

would not work?
