Embed watermark onto an image

[jarvis]

Hi All,

 

Hope someone can help. The below code displays a watermark over an image, how can I alter the code so it actually writes it on the image? Otherwise, you can download the pic and the watermark isn't on it.:

$imagesource =  $_GET['path']; 
$filetype = substr($imagesource,strlen($imagesource)-4,4); 
$filetype = strtolower($filetype); 
if($filetype == ".gif")  $image = @imagecreatefromgif($imagesource);  
if($filetype == ".jpg")  $image = @imagecreatefromjpeg($imagesource);  
if($filetype == ".png")  $image = @imagecreatefrompng($imagesource);  
if (!$image) die(); 
$watermark = @imagecreatefromgif('watermark.gif'); 
$imagewidth = imagesx($image); 
$imageheight = imagesy($image);  
$watermarkwidth =  imagesx($watermark); 
$watermarkheight =  imagesy($watermark); 
$startwidth = (($imagewidth - $watermarkwidth)/2); 
$startheight = (($imageheight - $watermarkheight)/2); 
imagecopy($image, $watermark,  $startwidth, $startheight, 0, 0, $watermarkwidth, $watermarkheight); 
imagejpeg($image); 
imagedestroy($image); 
imagedestroy($watermark);

 

Thanks again!

Hi, is this along the right lines:

$SourceFile =  $_GET['path']; 
function watermarkImage ($SourceFile, $DestinationFile) {

list($width, $height) = getimagesize($SourceFile);
$image_p = imagecreatetruecolor($width, $height);
$image = imagecreatefromjpeg($SourceFile);
imagecopyresampled($image_p, $image, 0, 0, 0, 0, $width, $height, $width, $height);

$src = imagecreatefromgif('watermark.gif');

imagecopymerge($image_p, $src, 0, 0, 0, 0, 800, 600, 75);

echo $SourceFile;

	if ($DestinationFile<>'') {
		imagejpeg ($image_p, $DestinationFile, 100);
	} else {
		header('Content-Type: image/gif');
		imagejpeg($image_p, null, 100);
	};

imagedestroy($image);
imagedestroy($image_p);

};

Thanks!
