Hi, first at all i want to say hello to all the forum people, this its my first topic here.

I have a big problem with a watermark script i use on my site, days ago i changed the host, and the new server has php5 instead php4,
the watermark script not longer works in php5,

File watermark.php

<?php

################################################## ###
$basedir="/home/lalala/public_html";
$watermarkimage="watermark.png";

################################################## ###
# end user modifiable stuff...

$file=basename($_GET['i']);
$path=($_GET['p']);

$image = $basedir."/".$path."/".$file;
$watermark = $basedir."/".$watermarkimage;

$im = imagecreatefrompng($watermark);

$ext = substr($image, -3);

if (strtolower($ext) == "gif") {
if (!$im2 = imagecreatefromgif($image)) {
echo "Error opening $image!"; exit;
}
} else if(strtolower($ext) == "jpg") {
if (!$im2 = imagecreatefromjpeg($image)) {
echo "Error opening $image!"; exit;
}
} else if(strtolower($ext) == "png") {
if (!$im2 = imagecreatefrompng($image)) {
echo "Error opening $image!"; exit;
}
} else {
die;
}

imagecopy($im2, $im, (imagesx($im2)/2)-(imagesx($im)/2), (imagesy($im2)/2)-(imagesy($im)/2), 0, 0, imagesx($im), imagesy($im));

if($_GET[repeat]) {
$waterless = imagesx($im2) - imagesx($im);
$rest = ceil($waterless/imagesx($im)/2);

for($n=1; $n<=$rest; $n++) {
imagecopy($im2, $im, ((imagesx($im2)/2)-(imagesx($im)/2))-(imagesx($im)*$n), (imagesy($im2)/2)-(imagesy($im)/2), 0, 0, imagesx($im), imagesy($im));
imagecopy($im2, $im, ((imagesx($im2)/2)-(imagesx($im)/2))+(imagesx($im)*$n), (imagesy($im2)/2)-(imagesy($im)/2), 0, 0, imagesx($im), imagesy($im));
}
}

$last_modified = gmdate('D, d M Y H:i:s T', filemtime ($image));

header("Last-Modified: $last_modified");
header("Content-Type: image/jpeg");
imagejpeg($im2,NULL,95);
imagedestroy($im);
imagedestroy($im2);

?>

htaccesss code

RewriteEngine on
RewriteBase /images
RewriteRule ^(img.*)/(.*\.[jJ].*)$ /home/lalala/public_html/wm.php?p=$1&i=$2

Any ideas about why this script not longer work?

Thanks in advance
best regards

Any error messages you are getting?

Thanks for reply

Fatal error: Call to undefined function imagecreatefrompng() in /home/lalala/public_html/watermark.php on line 19

Hm.. is GD library installed? If you are not sure, create a php file with just the phpinfo() command. This will show you if GD library is installed or not. You can ask your host as well

1. Not GD library but GD extension.
2. You should not use GD to manipulate images in php. Use imagemagick's command line utility named convert.

Why not just use Photoshop and just set the "Ocipacy" to 10-50.
