如何在Uploadify上傳時在每張圖片上創建水印？

我想用我自己的文本創建一個水印，例如。我想在每個圖像上創建「ABDULLAH」的水印。我在我的uploadify.php文件中有這些代碼行。如何在Uploadify上傳時在每張圖片上創建水印？

<?php 
if (!empty($_FILES)) { 
    $tempFile = $_FILES['Filedata']['tmp_name']; 
    $targetPath = $_SERVER['DOCUMENT_ROOT'] . $_REQUEST['folder'] . '/'; 
    $ext = end(explode(".", $_FILES['Filedata']['name'])); 
    $FileName = current(explode('.', $_FILES['Filedata']['name'])); 
    $originalFileName = $FileName.".".$ext; 
    $strRandNum = rand(0,99)+strtotime(date('YmdHis')); 
    $randomeFileName = $FileName."_".$strRandNum."_uid_".$_REQUEST['user_id']; 
    $completeFileName = $randomeFileName.".".$ext; 
    $dir_path = $_SERVER['DOCUMENT_ROOT'] . $_REQUEST['folder'] .'/'. $dirctory_name. "/"; 
    if((isset ($dirctory_name)) && ($dirctory_name != "") && (is_dir ($dir_path))) { 
     move_uploaded_file($tempFile,$dir_path.$completeFileName); 
    } 
    else { 
     mkdir($dir_path , 0777); 
     move_uploaded_file($tempFile,$dir_path.$completeFileName); 
    } 
    str_replace($_SERVER['DOCUMENT_ROOT'],'',$targetFile); 
} 
?>
