Hola duchamp:
Dime si te sirve esto:
Código PHP:
<html>
<head>
<title>
4 imágenes sin repetir
</title>
<script>
var imagenes = [
"http://www.sucaricatura.com/2002/maxi/2002H001.jpg",
"http://www.sucaricatura.com/2002/mini/2002H002.jpg",
"http://www.sucaricatura.com/2002/maxi/2002H003.jpg",
"http://www.sucaricatura.com/2002/mini/2002H004.jpg",
"http://www.sucaricatura.com/2002/maxi/2002H005.jpg",
"http://www.sucaricatura.com/2002/mini/2002H006.jpg",
"http://www.sucaricatura.com/2002/maxi/2002H007.jpg"
];
function azar() {
var temp = new Array(4);
temp[0] = Math.floor(Math.random() * imagenes.length);
do
temp[1] = Math.floor(Math.random() * imagenes.length);
while (temp[0] == temp[1])
do
temp[2] = Math.floor(Math.random() * imagenes.length);
while (temp[0] == temp[1] || temp[0] == temp[2] || temp[1] == temp[2])
do
temp[3] = Math.floor(Math.random() * imagenes.length);
while ( temp[0] == temp[1] ||
temp[0] == temp[2] ||
temp[1] == temp[2] ||
temp[0] == temp[3] ||
temp[1] == temp[3] ||
temp[2] == temp[3]
)
// alert(temp[0] + ", " + temp[1] + ", " + temp[2] + ", " + temp[3]);
document.images.imagen1.src = imagenes[temp[0]];
document.images.imagen2.src = imagenes[temp[1]];
document.images.imagen3.src = imagenes[temp[2]];
document.images.imagen4.src = imagenes[temp[3]];
}
</script>
</head>
<body onload=azar()>
<img src="" name=imagen1>
<img src="" name=imagen2>
<img src="" name=imagen3>
<img src="" name=imagen4>
</body>
</html>
Si lo pruebas, pon otras imágenes, porque algunas tienen bastante peso.
Saludos
