SPRY IMage SlideShow Basic: Auto create UL LI list

Question

Hope this is of some help to someone.
Recently moved from CS3 to CS5. So new to the whole DW widget thing.
I wanted a basic (no thumbs or titles) slideshow that will auto update when new images are added or removed from an image folder so I don't have to constantly edit the slideshow <UL> list each time I add or remove an image from the image folder/dir
My solution:
I replaced the <UL><LI></LI></UL> code block in my slideshow web page with some php code that will auto create the <UL> list from a folder of images.
I created a folder with only my slideshow images. (.png, .gif and/or .jpg only).  I now can add/remove image files from this folder and my slideshow updates automatically.
Seems to work well. My use is for a simple slideshow with no titles or thumbs.
web page code that has replaced the <UL></UL> block of images to display.
add to the top of your slideshow html page (
<?php
require('includes/dir2ul.php');  // path to where you put the dir2ul.php functions file
?>
replace your slideshow webpage SPRY Basic Slideshow  <UL> block with the code below with the changes commented with !! Important
<?php
//  Fill in the <UL> needed by Spry basic slideshow widget with a php dump of all files in a directory ending with .PNG/.GIF/.JPG to a <LI> element list
$my_dir = './my_slideshow-1/';        //!!!! IMPORTANT: change to your slideshow image directory path as shown  (yes, ends with a slash)
$spry_slideshow_id= 'SPRY_ImageSlideShow_3';  //!!!! IMPORTANT: change to your SPRY slideshow ID
dir2ul($my_dir, $spry_slideshow_id);
?>
The php function dir2ul.php (and support functions) code you need to require at the to of the slideshow page.
Put this code in a file named dir2ul.php (as used in this example) and save it somewhere that you include (require) in your slideshow web page.
<?php
function dir2ul($my_dir, $spry_slideshow_id)  {
//  Fill in the <UL> needed by Spry basic slideshow widget with a php dump of all files in a directory ending with .PNG/.GIF/.JPG to a <LI> element list
// $my_dir  :  image directory
$dir_handle= opendir($my_dir);
if (!$dir_handle) {
  print '<p>ERROR opening directory specified: ' . $my_dir . '</p>';
else  {
  //success opening directory
  /* loop thru the directory. */
  print '<UL id=' . $spry_slideshow_id . '>';
  while (false !== ($file = readdir($dir_handle))) {
     //  !!works best/faster if you keep your image directory all files. is_dir not a perfect check!!
     if(!is_dir($file) && ($file != ".") &&  ($file != ".."))  {   
       // !!!!IMPORTANT: change if needed. Only select files ending with .JPG, .JPG, or .PNG (case insensitive!)
       if(EndsWith($file, '.JPG')  || EndsWith($file, '.GIF')  || EndsWith($file, '.PNG') ){
         print '<li><img src="' . $my_dir  . $file . '"/></li>';  
     else {
        // directory: ignore (not recursive)   
       //print '<p> >> Directory: ' .  $file . '\n</p>';
   }  // while
   echo '</UL>';
}  //else
function EndsWith($FullStr, $EndStr) {
     // Get the length of the end string
     $StrLen = strlen($EndStr);
    $FullStrEnd = substr_compare($FullStr, $EndStr, -$StrLen,  $StrLen, true);   // case insensitive
    //$FullStrEnd = substr($FullStr, strlen($FullStr) - $StrLen);   // case sensitive
    //print '<br>  >>FullStr=' . $Full_Str . '  >>EndStr='  .  $EndStr . '  >>-StartPos=' . -$StrLen . ' >>length_to_compare=' .  $StrLen . ' >>return=' . $FullStrEnd;
    return $FullStrEnd == $EndStr;
function is_dir_LFS($path){
  return (('d'==substr(exec("ls -dl '$path'"),0,1))?(true):(false));
?>

I don't know what to say....I tried all night it didn't work. As soon as I posted my question on the forum the slideshow starts running....wow....I'm speechless. Thanks all who's looked at my post.
