Description:
------------
Hi i have started using imagejpeg function from GD. However, when i produce the following code: <see below>

It did not give save and overwrite my working image to a new image with a new size. please help me in this. Thanks

Reproduce code:
---------------
<?php
// The file
$filename = 'wew.jpg';

// Content type
header('Content-type: image/jpeg');

// Get new dimensions
list($width, $height) = getimagesize($filename);
$new_width = 10;
$new_height = 10;

// Resample
$image_p = imagecreatetruecolor($new_width, $new_height);
$image = imagecreatefromjpeg($filename);
imagecopyresampled($image_p, $image, 0, 0, 0, 0, $new_width, $new_height, $width, $height);

// Output

imagejpeg($image_p);
?> 

Expected result:
----------------
I expected to see my file : "wew.jpg" to be of size 10 x 10 pixels.

I realised that after trying my script for many times, i managed to get the file overwritten. It became a file of the same filename but of a new assigned size (10 x 10).

Please help as i don't seem to make it work again.

Actual result:
--------------
Actual result is that the browser did show me the small (10x10) picture but the real wew.jpeg is still untouched. I want it to be affected by the php code.
