Как сохранить и получить изображение из базы данных с помощью Pymongo?

Question

Я сделал сохранение изображения в базе данных с помощью командной строки, а также получил его с помощью команд put и get, но мы работаем над проектом python, и я хочу сделать это вручную с помощью pymongo.поэтому, пожалуйста, помогите мне.

видите, я пытался сделать это через cmd, а также пытался использовать команду os.path.join, но это показывает ошибку, и я думаю, что это не может быть сделано так.

вижу, что мой код графического интерфейса выглядит следующим образом: я хочу добавить его к базе данных в mongodb, используя Pymongo:

if __name__ == '__main__':

это должно показать изображение магазина на одном из четырех прямоугольников (получено наодин из 4 прямоугольников)
