Файл изображения CodeIgniter не может быть загружен

Одна проблема, которую я не могу решить во время, я пробовал все возможные решения, но я не очень хорошо. Ну, проблема в том, когда я хочу загрузить изображение, я выбираю изображение из моего комп и когда я нажимаю кнопку «Отправить», изображение не загружается, и это показывает мне изображение defaule, которое я помещаю в случай, когда пользователь не выбирает изображение (noimage.jpg). Функция загрузки изображения начинается с метода create ()
