Нужна помощь по загрузке файлов

Привет, У меня есть код в addnews.php он отвечает за загрузку скриншотов он работает.

Проблема в том что он не выводит ошибки при загрузке к примеру:

Мне нужно выводить сообщение если пользователь пытается загрузить слишком большой скриншот.

Помогите кто знает, вот сам код.
