Rotate images at timed intervals

[snorky]

How do I rotate images (or banners...)  every n seconds?

 

I use the following code to rotate the images every time the page is loaded. However, I want to rotate the images every n seconds while the page is displayed.

<?php
/*	
---------------------------------------------------------------------------------	
find all files (in this case images) in a folder 
and rotate randomly when page is loaded or refreshed 
note: as written here, all files must be valid images and there can be no sub-folders
---------------------------------------------------------------------------------
*/

$filenum=0;								// initialize counter
$pix=array();							// create array
$usedir="../images/const/";				// show location of images to rotate
if ($handle = opendir($usedir))			// open folder for reading
{
    while (false !== ($file = readdir($handle))) 
 {
        if ($file != "." && $file != "..") 
	  {
            $file=$file++;				// increment the counter
			$pix[]=$file;			// select the next element from the array
        }
    }
    closedir($handle);
}

shuffle($pix);							// shuffle the elements of the array
$displ1=$pix[1];						// create var to id image to display
$displ2=$pix[2];						// damphyno why I did this
print									// display the randomly-selected image

"<img src='" . $usedir.$displ1 . "'><br />\n";  
?>

[*]Refresh the page, then repeat, repeat ....

php doesn't do anything after the page is loaded... you'd have to use javascript or flash
