buttons doesn't show in t:datascroller

[Brummeline Braaten]

I use a t:datascroller to scroll between pages in a t:datatable. 
The problem is that the buttons for fast forward, next, back etc 
isn't rendered in my page. I have the pictures for the buttons in my 
project and the path is correct. I do not get any error messages. 
The datascroller work because I get the pagenumbers and I can change page by 
clicking on them. How can I get the buttons to show on my page?
