Я сделал код для загрузки изображений (более 1 в один клик) при загрузке миниатюры изображений хочу создать и сохранить в отдельной папке ... в моем коде загрузка изображений работает отлично, также генерируется первое изображение миниатюр в папку с миниатюрами, остальные миниатюры не генерируются .. выдает ошибку
Это мое изображение загрузки и создания эскиза кода
