class.upload.php is a powerful and mature PHP class to manage uploaded files, and manipulate images in many ways. The script is available under a GPL license.
I think that you can set a blacklist of file extensions in your php.ini, and the files having such extensions will be blocked during an upload. So the message is somehow right: "file upload stopped by extension" reads as "the file upload has been cancelled as the extension is forbidden".
