Очень хороший пример плавного появления картинки . Да простит меня автор я подправил только значение Step в функции
Для более плавного появления картинки. Интересно что пример работает с проблемным форматом - png -
Вопрос к знатокам а можно ли этот пример как то упростить? например вместо - png - поставить - gif - или какими-другими способами , или нельзя?
