Thumbnail Image

[xyn]

Hey;

I've been trying to get my thumbnail script to work.

There are no errors produced, however the thumbnail

isnt being created, the dimentions are the same as the

original image.

 

I was hoping for advise on where the problem is, and how

to get around it; my code:

<?php
include_once($_SERVER['DOCUMENT_ROOT']."/config.inc.php");
$img_base   = $_SERVER['DOCUMENT_ROOT']."/images/uploads/";
$max_width  = base64_decode(Secure($_GET['w']));
$max_height = base64_decode(Secure($_GET['h']));
$image_file = base64_decode(Secure($_GET['s']));
$image_path = $img_base.$image_file;

$img = null;
$ext = strtolower(end(explode('.', $image_path)));
if($ext == 'jpg' || $ext == 'jpeg')
{
    $img = @imagecreatefromjpeg($image_path);
}
elseif($ext == 'png')
{
    $img = @imagecreatefrompng($image_path);
}
elseif($ext == 'gif')
{
    $img = @imagecreatefrompng($image_path);
}
if($img)
{
    $width  = imagesx($img);
    $height = imagesy($img);
    $scale  = min($max_width/$width, $max_height/$height);

    if ($scale & 1)
{
        $new_width  = ceil($scale * $width);
        $new_height = ceil($scale * $height);
        $tmp_img = imagecreatetruecolor($new_width, $new_height);
        imagecopyresized($tmp_img, $img, 0, 0, 0, 0, $new_width, $new_height, $width, $height);
        imagedestroy($img);
        $img = $tmp_img;
    }
}
/*
if(!$img)
{
#NO IMAGE _ CREATE _ ERROR _ IMAGE
}
*/

header("Content-type: image/jpeg");
imagejpeg($img);
?>

 

The image code:

image_thumb.php?s=NDg4MTNiOWU5MDY2YTFkOTQ0YjBiNTk4NDhiMTYxYjhmNGM5MGE1ZjJiNzViMzAwY2I5N2RlMTEzMmIzNTczYmQ0ZjE5MmIxLnBuZw==&w=MTAw&h=OTg=

OK; I narrowed the error down a little:

if($img)
{
    $width  = imagesx($img);
    $height = imagesy($img);
    $scale  = min(ceil($max_width/$width), ceil($max_height/$height));

    if ($scale & 1)
    {
        $new_width  = ceil($scale * $width);
        $new_height = ceil($scale * $height);
	die($new_width."x".$new_height);
        $tmp_img = imagecreatetruecolor($new_width, $new_height);
        imagecopyresized($tmp_img, $img, 0, 0, 0, 0, $new_width, $new_height, $width, $height);
	$img = $tmp_img;
    }
}

 

$scale returns "1"

which means its multiplying the current W/H by 1

ie why it doesnt change the size.

 

any ideas?

what are the values for $max_width and $max_height?
