关于给图片加水印
我写了一个采集程序 采集网上的图片 采集回来的是一堆乱码字符
header("Content-type:image/jpeg;charset=utf-8");之后能显示正常图片
现在我想给图片加上水印
我是把采集的图片直接保存到目录上  然后再加载按下面方式处理
$fp = @imagecreatefromjpeg(图片路径);
$wp = @imagecreatefrompng(水印路径);
$res = imagecopy($fp,$wp,0,0, 0, 0,120,180);
imagejpeg($fp);
现在我想不保存到目录 直接加上水印在页面上显示该如何处理 请大家指教一下 谢谢


------解决方案--------------------
不是有 imagecreatefromstring 吗?
$fp = imagecreatefromstring(file_get_contents('http://avatar.profile.csdn.net/9/D/6/1_dream1206.jpg'));<br />$wp = imagecreatefromstring(file_get_contents('http://avatar.profile.csdn.net/1/5/6/1_gilper.jpg'));<br />imagecopymerge($fp,$wp,0,0, 0, 0,120,180, 50);<br />imagepng($fp);
Copy after login
