prev/pause/next

I’d like to add custom navigation to the background manager.
This is my html:
Is there a way to make this work?

<nav class="slider-nav">
    	<a href=""><img class="prev" src="/images/nav-slider-prev.png" alt="prev" /></a>
    	<a href=""><img class="pause" src="/images/nav-slider-pause.png" alt="pause" /></a>
    	<a href=""><img class="next" src="/images/nav-slider-next.png" alt="next" /></a>
    </nav>
