pretty cool though, i may look into it

Yes he is using curl.
This can be done much easier with fopen.

I have not Installed this hack, or tested my file change.. It should work though.

Replace the Code he gives in the install file with this.

PHP Code:

        if (is_array($_POST['attachmenturl']))
        {
            foreach ($_POST['attachmenturl'] AS $key => $url)
            {
                // attempt to fetch the filename from the url
                preg_match('/\/([A-z0-9]*)([\.]{1})([A-z0-9]{2,6})$/si', $url, $matches);
                $filename['original'] = str_replace("/", "", $matches[0]);

                // did we retrieve a valid filename?
                $validurl = iif(!empty($url) AND !empty($filename['original']), true, false);

                /*
                 * FOPEN Modification By Trigunflame
                 */
                // valid url
                if ($validurl)
                {
                    // init
                    $data = '';

                    // cancel the file that might have been uploaded
                    unset($_FILES["attachment{$key}"]);

                    // attempt opening of remote file
                    if ($fileOpen = @fopen($url, "rb"))
                    {
                        while (!feof($fileOpen))
                        {
                            $data = @fread($fileOpen, 4096);
                        }
                        @fclose($fileOpen);
                    }

                    // empty
                    if (empty($data))
                    {
                        $error = construct_phrase($vbphrase['error_cannot_retrieve_url'], $url);
                        $errors[] = array(
                            'filename' => htmlspecialchars_uni($url),
                            'error' => $error
                        );
                    }

                    // save file
                    else
                    {
                        $tmp_name = 'vbupload' . substr(TIMENOW, -4);
                        $filesize = strlen($data);
    
                        // write file to temporary directory...

                        {
                            // ... in safe mode
                            $filename['temp'] = $vboptions['tmppath'] . "/$tmp_name";
                            $filenum = @fopen($filename['temp'], 'wb');
                            @fwrite($filenum, $data);
                            @fclose($filenum);
                        }
                        else
                        {
                            // ... in normal mode
                            $filename['temp'] = tempnam(ini_get('upload_tmp_dir'), 'vbupload');
                            $fp = @fopen($filename['temp'], 'wb');
                            @fwrite($fp, $data);
                            @fclose($fp);
                        }

                        $_FILES["attachment$key"]['name'] = $filename['original'];
