how to add more posts to facebook like box plugin

I have used facebook’s likebox to add a facebook stream to our site. By enabling the “show posts” option you are showing some posts under the “LIKE” button and above the photos of others who already like that facebook profile.

My question is this – how do I expand the height of the “posts” section?
Simply by increasing the “height” attribute in the default code all I’ve done is increase the “photos” area below. Not the stream of posts.

I want more posts and less photos of users.

Thanks
