其实就是水印啦

//session_start();
header("Content-type: image/png"); //声明图片
//$image = imagecreate(417, 294);    //创建图片大小
$image = imagecreatefrompng("cj.png");
$admin = imageCreatefrompng("admin.png");

$wfilew=imagesx($image);//取得图片的宽
$wfileh=imagesy($image);//取得图片的高
$waterw=imagesx($admin);//取得水印图片的宽
$waterh=imagesy($admin);//取得水印图片的高

//$imgbg = imagecolorallocate($image,30, 30, 30);  //图片背景色彩
//imagefill($image, 10, 10, $imgbg);
$colorBlack = imagecolorallocate($image, 0, 0, 0);
$colorBlacks = imagecolorallocate($image, 144, 144, 144);


imagettftext($image, 20, 0,270, 250, $colorBlack, "simkai.ttf", "吕滔");
imagettftext($image, 12, 0,230, 424, $colorBlacks, "arial.ttf", "420528198602344812");

imagecopy($image, $admin, 550, 350, 0, 0, $waterw,$waterh);
//imagestring("2.jpg",2,3,10,$waterstring,$colorBlack);
//$_SESSION['lvtao']=$waterstring;
imagepng($image);
