Java Image Rotator Banner

19 Nov , 2007  

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  [email protected]

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.
