1. create a script with an array of image urls
2. use GET ie. www.page.com?img=1 method to post img number to page. on page load change the image based on this number.
3. use meta refresh or javascript to refresh after several seconds incrementing the GET img variable.

and that is how you would do it.
happy coding.

you cannot use javascript to do this unles syour using something like ajax. in which case you will require server side coding.

you could use AJAX to update the image every so many seconds.

google it and try some examples.
