эй, мне нужна помощь со следующим. У меня есть сайт, Хотя я не был на 100% программистом, я стараюсь ориентироваться в программировании сайта. Работает в asp.net 2.0.

У меня есть галерея изображений, но единственная проблема в том, что я могу загрузить только 1 изображение за раз. Мне нужна помощь, как я могу интегрировать несколько изображений на сайте.

ниже - код для album.asp

К вашему сведению, эти страницы являются классическим ASP и не имеют отношения к недавно появившейся технологии ASP.NET.

Я не знаю, как решить вашу проблему, но давным-давно я использовал коммерчески доступный компонент SoftArtisans FileUp , чтобы обеспечить надежную загрузку нескольких файлов в классическом ASP.

Вы пробовали использовать несколько <input type="file">?

EDIT:

То, что вы также можете попробовать затем, - это динамическое создание IFRAME с полем ввода файла в нем и отправка этой формы, хранение файла во временном местоположении на сервере и каким-то образом указание пользователю, что он загрузил один из файлы.
