Bonjour, je ne me connais pas trop en javascript, j'en ai récupéré un script sur le net et j'aimerai le paramétrer avec des nouvelles valeurs.
Comment faire??

c'est facile, tu changes la valeur des variables qui correspondent à tes paramètres.

j'ai essayé mais ça me vhange tout voici le script si tu peux me montrer comment faire ce script est paramétré pour cinq image de chaque coté moi je veux en mettre 15 de chaque coté merci
