Здравствуйте! Имеется код, благодаря которому производится загрузка и удаление изображений из каталога на сайте. После загрузки изображения, они выводятся на экран, показывая, какие изображения имеются на данный момент в каталоге. Задача: сделать так, чтобы выводились только те изображения, имя которых есть в БД или хотя бы найти место, которое отвечает за вывод изображений из каталога. Добавлено через 48 секундСобственно сам код: | Код |
