Bonjour, je voudrais faire une gallerie en javascript,
j'ai récupérer un code sur http://www.dhteumeuleu.com/, mais j'aimerais qu'au lieu de me faire des grille de 4*4 ou 6*6 ...
qu'il me fasse des grille d'un chiffre*5 mais le code est trop compliquer pour moi, j'y comprend pas grand
si vous pourrez m'aidez a m'en sortir
Merci d'avance
le code :

c'est bon j'ai réusi, c'était juste une histoire de boucle: je met pour ceux que ça interresse,
extrait du code :
ce qui change est en rouge
/* init script */
init : function ()
{
this.screen.obj = document.getElementById('screen');
var img = document.getElementById('bankImages').getElementsByTagName('img');
this.screen.obj.onselectstart = function () { return false; }
this.screen.obj.ondrag = function () { return false; } /* create images grid */
var ni = 0;
var n = (tv.grid.size / 2)- .5;
for (var y = 0; y <= 4; y++)
{
for (var x = -n; x <= n; x++)
{ /* create HTML image element */
var o = document.createElement('img');
var i = img[(ni++) % img.length];
o.className = 'tvout';
o.src = i.src;
tv.screen.obj.appendChild(o); /* 3D coordinates */
o.point3D = {
x : x,
y : y,
z : new Library.ease()
};
