Proszę o pomoc: Chcę stworzyć na swojej stronę galerię zdjęć, aby gdy kliknę na pojedynczy obrazek nastąpiło jego otwarcie w pełnym formacie, ale nie na nowej karcie, tylko tak jak to jest na stronie www.lagwa.pl – nawet bez opisu, tylko sam podgląd. Ja nie znam JS, więc proszę o najprostsze rozwiązanie i kod html. Z góry wielkie dzięki

Lightbox vel fancybox.

Czy możesz mi opisać najprotszy proces jego instalacji?

Pedro84 · 16-07-2010, 02:18

Poszukaj skryptu, zajrzyj do dokumentacji, przecież to czasem polega na dołączeniu js i nadaniu klasy <img>...
