Я ТЕБЕ СКИНУЛ НА ПОЧТУ!!!
Для Тех кому нужен скрипт "ДЛЯ УВЕЛИЧЕНИЕ КАРТИНОК ПРИ КЛИКЕ НА НЕЁ", пишу статью!
Поехали:
Для начала нам нужно создать 2 папки (1-я папка для хранение картинок (которые будем использовать для увеличения), 2-я папка для css и js и 5 готовых картинок).
1) Папка (img):
1.awp.jpg
2.awp_mini.jpg
2) Папка (zoom):
1.zoom-x.gif
2.zoom-x.png
3.zoom-load.gif
4.zoom-shadow.gif
5.zoom-shadow.png
6.zoom.js
7.zoom.css
8.jquery.min.js
3) Создадим файл - test.html
