Hôm nay mình xin chia sẻ cùng các bạn thủ thuật tạo Slideshow cho hình ảnh, thủ thuật này mình có thêm hiệu ứng Sroll với 2 mũi tên điều khiển qua lại các ảnh thumb bên dưới các hình ảnh lớn được trình diễn. Bài viết này mình tham khảo code slideshow của nitinh.com, tuy nhiên với slideshow đó thì không có hiệu ứng scroll cho các ảnh thumb. Đây là cái gây khó khăn và phiền phức khi bạn muốn trình diễn với số ảnh nhiều hơn. Nếu không để chế độ Scroll thì ảnh thumb của bạn sẽ dài lê thê. Vì vậy mình kết hợp với JQuery CarouselLite để cho tiện ích trở nên hoàn thiện hơn.Hình ảnh minh họa

6. Save template lại và trở về phần tử trang (Page Elements)
7. Thêm 1 HTML/Javascript và thêm vào code bên dưới

Các ảnh bên dưới phần bigPic bạn thay thành các link ảnh lớn tương ứng với các ảnh thumbnail trong phần thumbs. Như vậy là xong.
8. Cuối cùng save tiện ích lại
Chúc bạn thành công
