Today a lot of people are doing this with Flash … back in the day I did it old school with Java.
/*
java_banner.java ver 1.1 (Final Release)
Barry Wise, 10/98
Version 1.1 Final Release 2/1/2000
This applet is freeware. For minimal support and customizations, please contact
the author at bwise@cybernex.net.
Source supported at: http://www.barrywise.com/
This Java applet is designed to work in all browsers which support Java, namely IE 3+ and Netscape 2+.
It cycles through a number of images (as many as you want). There are only a few parameters to set:
applet_speed: The number of milliseconds before the next banner image loads (Cannot be less than 500)
background_color: Set this to your page's background color in HEX format (i.e. FFFFFF = white).
border: Set to 0, nothing. Set this to 1 if you want a small black border around all the images.
number_of_links: The number of images and links you have specified.
pageLink0, pageLink1, etc.: The URL for each corresponding image (unlimited number of links available).
imageSrc0, imageSrc1, etc.: The Banner Image to correspond with each URL in pageLink, also unlimited.
