how to dynamically read in local files?

I made an image slideshow of sorts for a website. Right now each slideshow image is a list item stored in a unordered list and I use javascript and naming conventions to write each list item out. Example: 

for (j = 0; j<imageFileLength; j++){
    $('ul#Slider').append('<li><img src="'+fileName+'/0'+j+'.png" /></li>');} //write list items for each image
 });

This worked for awhile but now I can't hardcode it like this anymore. Anyone needs to be able to drop files into my folder, favorably with any name, and they will automatically be added as a list item to the unordered list.

I am required to use IE 8 which is a bit of a problem. It doesn't support the HTML File API, and it also doesn't support using PHP, but I might be able to get this turned on.

Any ideas? Or, if PHP is a good way to go about it, how it would be done? Maybe java via netbeans?

thank you

Here is the code which is being used and works without any issue.

$folder = 'images/';
$filetype = '*.jpg'; /* use the file extension you would read; here its jpg file */
$files = glob($folder.$filetype);
$count = count($files);
echo '<ul id="slider">';
for ($i = 0; $i < $count; $i++) {
    echo '<li>';
    echo '<img src="'.$files[$i].'" />';
    echo substr($files[$i],strlen($folder),strpos($files[$i], '.')-strlen($folder)); /* display name of the file */
    echo '</li>';
}
echo '</ul>';

Look at http://php.net/manual/en/function.dir.php

in the documentation was the following example, which should set you on the path you're looking for:

<?php
$d = dir("/etc/php5");
echo "Handle: " . $d->handle . "\n";
echo "Path: " . $d->path . "\n";
while (false !== ($entry = $d->read())) {
   echo $entry."\n";
}
$d->close();
?>

The above example will output something similar to:

Handle: Resource id #2 Path: /etc/php5 . .. apache cgi cli
