Is it possible to load random jpeg files every time a page is visited. ie- every time the page is viewed, a random image is displayed instead of the usual image.
Cheers

You can use a script to do this, either Client Side (via javascript) or Server Side. See http://209.68.38.102/limo/randpic.php for a script I wrote that lets me have changing icons in another forum I frequest.
The code for the PHP one is:
<?$randval = rand(1,4); // generate a number from 1 to 4
$fname = "limo-0" . $randval . ".jpg";
$fp = fopen ($fname, "r");
while (!feof ($fp)) echo fgetc($fp);
fclose($fp);
?>
'
I have this code in a directory (limo) and also have 4 images in there, limo-01.jpg, limo-02.jpg, limo-03.jpg and limo-04.jpg.

or if you don't have php... here's a javascript version:
<script language="JavaScript"><!--
function random_imglink(){
var myimages=new Array()
//specify random images below. You can have as many as you wish
myimages[1]="image1.gif"
myimages[2]="image2.gif"
myimages[3]="image3.gif"
myimages[4]="image4.gif"
myimages[5]="image5.gif"
myimages[6]="image6.gif"
var ry=Math.floor(Math.random()*myimages.length)
if (ry==0)
ry=1
document.write('<img src="'+myimages[ry]+'" border=0>')
}
random_imglink()
//-->
</script>
'
Simply place it in your HTML anywhere between the body tags and update the image links in the array where prompted.

You mean the following jibberish?

What that script is doing is opening the actual image file, and writing all the data into the browser, and the browser should read it, BUT you should add
<?header("Content-Type: image/jpg");
$randval = rand(1,4); // generate a number from 1 to 4
$fname = "limo-0" . $randval . ".jpg";
$fp = fopen ($fname, "r");
while (!feof ($fp)) echo fgetc($fp);
fclose($fp);
?>
'
<? echo implode('',explode('|','A|W|E|S|O|M|E')); ?>
