display random image in the same page?

[hisham]

How can I display random image in the same page?
Every time some body requests a php page, this will display different image from the images folder. Hope someone can help.
Thanks in advance.

<?php
// Directory goes here relative to script (fs = file system; ws = web server directory)
$image_fs_dir = '/absolute/path/to/images'; // without trailing slash
$image_ws_dir = '/web/path/to/images/';  // with trailing slash
$href_link = '[URL unfurl="true"]http://www.ironorchid.com/clipart/';[/URL] // What your link points to (optional)

$handle = opendir($image_fs_dir);
while (false !== ($file = readdir($handle))) {
  if (preg_match(&quot;/\.(jpe?g|gif|png)$/i&quot;, $file)) {
    $filelist[] = $file;
  }
}
closedir ($handle);

srand((double)microtime()*1000000);
$picnum = rand(0, sizeof($filelist) - 1);

$content = '<div align=&quot;center&quot;>';
if ($href_link != '') {
  $content .= '<a href=&quot;' . $href_link . '&quot;><img src=&quot;' . $image_ws_dir . $filelist[$picnum] . '&quot; border=0></a>';
} else {
  $content .= '<img src=&quot;' . $image_ws_dir . $filelist[$picnum] . '&quot; border=0>';
}
$content .= '</div>';
