    Hi, using Math.random(), I need to show one of six pictures every time I reload the page. I need to use the while loop too.

    So far I have this, but it only shows four of the six pictures I have.

    <script language="JavaScript">

var random = Math.random() ;
var picnum = Math.round(random*4)+1;

</script>
</head>

<script language="JavaScript">

document.write('<img src=picture/film'+picnum+'.jpg>')



</script>
    HTML:
    Thanks for your help! :eek:

    Of course it works... Unless you're using a very old browser it works flawlessly...

    create a html page with just this in it:

    
<html>
<head></head>
<body>
<script>
var picnum = parseInt(Math.random() * 6) + 1;
alert(picnum);
</script>
</body>
</html>
    Code (markup):
    then open it, and refresh it many times... you'll always get a number between 1 an 6.

    If it still doesn't work for you, consider enabling javascript on your browser...
