Add watermark to image

[nicutdk]

Hi,

I have this script and works fine with images files.

I change files storage from database to directory "attach".


.htaccess

RewriteEngine On
RewriteCond %{REQUEST_FILENAME} -f
RewriteRule .(attach)$ /attach/1/watermark.php [QSA,NC]

watermark.php

PHP Code:

<?php 
$path = $_SERVER['DOCUMENT_ROOT'].$_SERVER['REQUEST_URI']; 
$image = imagecreatefromstring(file_get_contents($path)); 
$w = imagesx($image); 
if ($w > 50) { 
$h = imagesy($image); 
$watermark = imagecreatefrompng('watermark.png'); 
$ww = imagesx($watermark); 
$wh = imagesy($watermark); 
imagecopy($image, $watermark, $w-$ww, $h-$wh, 0, 0, $ww, $wh); 
} 
header('Content-type: image/jpeg'); 
imagejpeg($image); 
exit(); 
?>

I see watermark at this address

But at this address watermark not working. WHY ? it is the same file.

Please help me with that.

Best Regards,
