我们经常看见好多网站上的图片有水印，例如新浪、腾讯上的一些图片上写着版权所有。这就是水印。下面我用php代码简单制作水印，希望对大家有所帮助

<?php
// Load the stamp and the photo to apply the watermark to
$stamp = imagecreatefrompng('http://www.100sucai.com/img/qq.png');
$im = imagecreatefromjpeg('http://www.100sucai.com/img/qq.jpg');

// Set the margins for the stamp and get the height/width of the stamp image
$marge_right = 10;
$marge_bottom = 10;
$sx = imagesx($stamp);
$sy = imagesy($stamp);

// Copy the stamp image onto our photo using the margin offsets and the photo 
// width to calculate positioning of the stamp. 
imagecopy($im, $stamp, imagesx($im) - $sx - $marge_right, imagesy($im) - $sy - $marge_bottom, 0, 0, imagesx($stamp), imagesy($stamp));

// Output and free memory
header('Content-type: image/png');
imagepng($im);
imagedestroy($im);
?>
