Well u can do something like this.
Whole code here -> http://pastebin.com/Xxx4urR9
Demo here -> http://sorlakertest2.hostzi.com/1-sliderndescription/
This is an example code of your slider contents.

PHP Code:

$div = array(
            "images" => array(
                0 => "http://image.naldzgraphics.net/2012/09/15-the-abstract.jpg",
                1 => "http://www.inspirationmix.com/wp-content/uploads/2010/11/abstract-colorful-background-green-2.jpg",
                2 => "http://www.kkuodesign.com/wordpress/wp-content/uploads/2010/07/iphone-wallpaper-abstract-design-71.png",
                3 => "http://cdn.instantshift.com/wp-content/uploads/2012/10/abstract-and-light-effect-tutorials-55.jpg",
                4 => "http://cdn.instantshift.com/wp-content/uploads/2012/10/abstract-and-light-effect-tutorials-21.jpg"
            ),
            "descriptions" => array(
                0 => "Desc1",
                1 => "Desc2",
                2 => "Desc3",
                3 => "Desc4",
                4 => "Desc5"
            )
        ); 


N this is the jquery function.

$(function (){		
		var numberOfImages = <?php echo count($div['images']); ?>;
		var images = new Array();
		var descriptions = new Array();
		<?php
		for($i = 0; $i < count($div['images']); $i++) {
			echo "images[".$i."] = \"".$div['images'][$i]."\";\n";
			echo "descriptions[".$i."] = \"".$div['descriptions'][$i]."\";\n";
		}
		?>
		function sortImages(){	
			var randomNumber = Math.floor((Math.random() * numberOfImages)); //this will get a random number from 0 -> numberOfImages - 1
			//alert(randomNumber);
			$('#slider').css("background-image", 'url("'+ images[randomNumber] +'")');
			$('#sliderDescription').html(descriptions[randomNumber]);
		}
		sortImages();
		setInterval(function (){sortImages()}, 1000); // the background will change every 5 seconds.
	});

Another way is to display all the images n do that .hide() .show() .fadeIn() .fadeOut thing as we do in jquery.
