For example, in this url: `https://graph.facebook.com/shaverm/picture?redirect=false`, the id is "shaverm". But the id can also be a graph id, like 376995711728. So you would use it like so:

```js
var params = {
  id: 'shaverm',
  access_token: 'FB-ACCESS-TOKEN',
  redirect: false
}

client
.use('fb')
 .get(':id/picture', params, function (err, res, reply) {
   console.log('reply', reply)
 })
```
