I have an image processing script to upload different types of graphic files.  I am able to create an alpha layer png file as well as its thumb for viewing.  I can also upload Illustrator and Photoshop files and create a png thumb for viewing, however I have not figured out how to create the Alpha thumb on the Illustrator and Photoshop files, the code below is used to process the thumbs can anyone help with the alpha png thumb from the photoshop and Illustrator files.  I'm missing something.  Thanks in advance for your time and effort.

 

<?php
include_once('classPhpPsdReader.php');
function showUploadError() {
echo '<p style="color:red;font-weight:bold;">You have attempted to upload an image that is not a non-progressive JPG,
    OR the JPG extensions are not enabled in your GD library. You will not be able to use the image that you attempted
    to upload.</p>';   //non-progressive Jpg now supported
}
?>
  <?php
// Finally display the PSD on the screen

    // Generate thumbnail
function makeThumb($file, $thumbnail, $size) {
   global $message;

   if(file_exists($file)) {
     list ($width, $height) = GetImageSize ($file);

     if ($width > $height) {
         // Width greater than height
         $newWidth  = $size;
         $newHeight = ($newWidth * $height) / $width;
     } else {
         // Height greater than width
       $newHeight = $size * .8;
       $newWidth  = ($newHeight * $width) / $height;
     }
     
// this error suggests that a non JPG was uploaded Progessive JPEG's are now allowed
// OR that JPG support is not enabled in PHP, use error to upload PNG file
