En primer lugar, gracias por el tiempo.
Vamos a ello.
Estoy creando una web que tiene una imagen de fondo que cambia cada x tiempo con un barrido. Esta función de JS me funciona bien en Opera, Safari, IE...pero en Firefox no hay manera.
Con la consola detecté un error de getelementbytagname que ya está solucionado. Ahora el FF no me da error, pero sigue sin verse nada de nada.
Les dejo los códigos aquí abajo por si pueden echarme un cable.
El JS.
