RobertJurco on "How to create simple slider"

Hello all,
I'm creating a custom wordpress theme for my project and I need to create absolutely simple slider but don't know how to do it.
I have the following HTML code created:

<ul class="slides">
			    <li>
			      <img src="<?php print IMAGES; ?>/slider.png" alt="Slide1">
			      <h2>Heading</h2>
			      <p>
			      	 Description
			      </p>
			    </li>
			    <li>
			      <img src="<?php print IMAGES; ?>/slider.png" alt="Slide2">
			      <h2>Heading</h2>
			      <p>
			      	Description
			      </p>
			    </li>
			    <li>
			      <img src="<?php print IMAGES; ?>/slider.png" alt="Slide3">
			      <h2>Heading</h2>
			      <p>
			      	Description
			      </p>
			    </li>
			  </ul>

I don't need any administration for slider, it should only display for example 5 newest posts. Background image should be featured image.
Any idea how to do this?
Thank you all for help!
