Невозможно обновить изображение в formview

мне понадобится твоя помощь. Я написал код для обновления изображения в форме. Все работает нормально. Но при загрузке изображения из любого другого места на компьютере я сразу же нажимаю на кнопку «Обновить» и получаю сообщение об ошибке: «Не удалось найти файл C: \ Program Files \ IIS Express \ FariPassport.jpg». Это моя страница aspx:
