help with thumbnail function

[Nick]

Here is what I have, and it works nicely. But I need help creating the PNG part of it, as of right now it will only create thumbnails for jpgs.

<?php

function create_thumbnail($image, $path) {
    $thumb = $path . "thumb_" . $image;
    $fullimage = $path . $image;
    copy($image, $thumb);

    list($width, $height) = getImageSize($image);

    $len = strlen($thumb);
    $pos = strpos($thumb,".");
    $type = substr($thumb,$pos + 1,$len); 

    if($width > 100) {
        $quotient = ceil($width/100);
        $new_width = 100;
        $new_height = ceil($height/$quotient);
    } else {
        $new_width = 100;
        $new_height = $height;
    }

    if($type=="jpeg" || $type=="jpg") {
        $destimg = ImageCreate($new_width, $new_height);

        $srcimg = ImageCreateFromJPEG($thumb);

        ImageCopyResized($destimg,$srcimg,0,0,0,0,$new_width,$new_height,ImageSX($srcimg),ImageSY($srcimg));

        ImageJPEG($destimg, $thumb);
    } 
}

?>

Any help much appreciated

See imagecreatefrompng

So, for PNG...

$destimg = ImageCreate($new_width, $new_height); 
$srcimg = ImageCreateFromPNG($thumb); 
ImageCopyResized($destimg,$srcimg,0,0,0,0,$new_width,$new_height,ImageSX($srci  mg),ImageSY($srcimg));
ImagePNG($destimg, $thumb);
