Help with image and text

So i have an large image on my website, and i would like text in the middle of it.

<div class="img-background">
	 <img class="img-climb" src="img/climb.jpg.jpg" alt="no climber>
	  <p id="img-climb-text">Etiam malesuada ultricies donec ac velit a lorem luctus ultricies</p>

So how do i get the text to move up inte image area? and in the middle of it?
