I am using this code to display images in slide show and the selection of images is dynamically... But it is populating only the first image and does not fetch other images... Please guide me where is the error?

XML

PHP Code:
<?php
    header("content-type: application/x-javascript");

    function returnimages($dirname=".") {
        $files = array();
        $curimage = 0;

        //valid image extensions
        $pattern="(\.jpg$)|(\.png$)|(\.jpeg$)|(\.gif$)";

        if($handle = opendir($dirname)) {
            while(false !== ($file = readdir($handle))) {
                if(eregi($pattern, $file)){
                    echo 'galleryarray[' . $curimage . '] = "' . $file . '";';
                    $curimage++;
                }
            }

            closedir($handle);
        }

        return($files);
    }

    //Define array in JavaScript returnimages()
    //Output the array elements containing the image file names

    echo 'var galleryarray = new Array();';
?>

HTML Code:
<html>
    <head>
        <title></title>
        <script src="pics/getimages.php"></script>
        <script type="text/javascript">
            var galleryarray = returnimages();
            var curimg = 0;

            function rotateimages(){
                var imagesDirectory = "pics/" + galleryarray[curimg];
                document.getElementById("slideshow").setAttribute("src", imagesDirectory)
                curimg = (curimg < galleryarray.length - 1) ? curimg + 1 : 0
            }
            window.onload = function(){
                setInterval("rotateimages()", 2500)
            }
        </script>
    </head>
    <body>
        <img width="468" height="312" id="slideshow" src="..._web\pics\seal.jpg">
    </body>
</html>
