如何在没有任何PHP脚本的情况下上传图片？

<?php
$uploaddir = \'/myappname/uploads/\';
$file = basename($_FILES[\'userfile\'][\'name\']);
$uploadfile = $uploaddir . $file;

if (move_uploaded_file($_FILES[\'userfile\'][\'tmp_name\'], $uploadfile)) {
        echo \"http://www.mycompanywebsite.com/myappname/uploads/{$file}\";
}

?>
