Cześć!
Mam drobny problem ze skryptem galerii. Skrypt nie jest mój,jednak na jego podstawie chcę budować dalsza część skryptu.
Skrypt ma za zadanie wczytać pliki graficzne. I wczytuje je jak należy. Problem zaczyna się gdy chce zmienić ścieżkę odczytu.
Oryginalnie skrypt wczytuje obrazki z katalogu głównego. Jedyna zmiana jaką wprowadziłem w skrypcie to właśnie ścieżka opendir.
Pliki oczywiście wczytuje,ale już nie wyświetla obrazków. Nie potrafię za bardzo sobie z tym poradzić
Jakieś wskazówki?

Do działania skryptu wykorzystywany jest tez plik images. Próbowałem tutaj zmienić oryginalne ściezki ale i to nic nie dało,dlatego wrzucam plik oryginalny
