Hi there!
I have created a script the generates random pictures...
<?php
//Random pictures
//
$pictures[0] = "bil1.gif";
$pictures[1] = "bil2.gif";
$pictures[2] = "bil3.gif";
$pictures[3] = "bil4.gif";
for ($i=0;$i<3;$i++) {
$r = rand(0,3);
?>
<p> <img src="<?php echo $pictures[$r];?>"></p>
<?php
}
?>
With this above script the same picture can be shown twice. Is there any smart way of avoiding this without having to rely on cookies/sessionids?
Best regards
