How to modify number of faces in Facebook box

I tried to use a facebook-box, but the number of faces are limited to the height of the box. But there is a possibility to modify the number of fans in your Facebook like box.

You just have to modify your code:
.....data-show-faces="true" data-colorscheme="light" ...

In order to modify the number of contacts in your like-box, insert the following code:

  data-show-faces="true" connections="8" data-colorscheme="light"

You can also use a custom height adding: data-height="152" 

I hope you can use it.
