How would I display a Font-Awesome icon in a github wiki?

I tried to link to the source from the Font-Awesome site, but it just creates a link

eg:

```
| Element | Icon Name | Icon Image|
| ------- | ----------| ----------|
| chart | fa-line-chart | http://fortawesome.github.io/Font-Awesome/icon/line-chart |
| trash | fa-trash | http://fortawesome.github.io/Font-Awesome/icon/trash |

```
