请帮忙修改，我有把照片换成我自己的照片
<?php
header("content-type:image/jpeg");
$im=imagecreatefromjpeg("images/1.jpg");
$textcolor=imagecolorallocate($im,56,73,136);
$fnt="c:/windows/fonts/Tahoma.ttf";
$motto=iconv("gb2312","utf-8","长白山天池");
imagettftext($im,220,0,480,340,$textcolor,$fnt,$motto);imagejpeg($im);
imagedestroy($im);
?>
