    Добрый вечер. Есть скрипт загрузки фото (она правильно работает), но есть небольшая проблема:
    Когда фото загружается в Хроме выходит окно "Подтвердите действие на домен.ру". Как бы это окно убрать?
    И еще, напротив кнопки "выбора файла" есть надпись "Файл не выбран". Как бы ее убрать?
    В скрипте всего два файла.
    Первый файл:
    Код:
    <?php
        $error = "";
        $msg = "";

        if(!empty($_FILES[$fileElementName]['error']))
        {
            switch($_FILES[$fileElementName]['error'])
            {
    
                case '1':
                    $error = 'The uploaded file exceeds the upload_max_filesize directive in php.ini';
                    break;
                case '2':
                    $error = 'The uploaded file exceeds the MAX_FILE_SIZE directive that was specified in the HTML form';
                    break;
                case '3':
                    $error = 'The uploaded file was only partially uploaded';
