File size and dropbox add-on

Hello!

I think that I’ve found an issue in WPDM and Dropbox Add-on.
The public page that I’ve created for show my files uploaded from my dropbox account, shows files size of 0 for all files.
I’ve added some code in functions.php file at line 995

foreach ($vars['files'] as $f) {
            //Fix - Calc remote file size -> Es. Dropbox
            if ((stripos($f, 'https://') == 0) || (stripos($f, 'https://') == 0)){
                $headers = get_headers($f);
                $size += $headers['Content-Length'];
                foreach ($headers as $index => $value) {
                    $values = split(':', $value );
                    if ($values[0]=='Content-Length'){
                        $size += $values[1];
                    }
                }
            }//End fix
            else if (file_exists($f)){
                $size += @filesize($f);
            }
            else{
                $size += @filesize(UPLOAD_DIR . $f);
            }
        }

I hope it can help someone.
