This script uses dynamic html to display logo images and hyperlinks. Three images are displayed at a time. After every 10 seconds, the oldest logo is removed and a new logo is added.

To install, download the file logo.js. Add:

<script LANGUAGE="JavaScript" TYPE="text/javascript" src="logo.js"></script>

within the <head> of your web page. Where you want your logos displayed, add a table with <td id="p001"><td id="p002"><td id="p003">. In NS4, instead of <td id>, use <layer id>.

You also need to define your logo list in public arrays.

Public Variables:
wid[] - <img width>
hgt[] - <image height>
img[] - image cache
src[] - <img src>
tit[] - <img alt>
url[] - <a href>

wid = new Array() ; hgt = new Array() ; img = new Array()
src = new Array() ; tit = new Array() ; url = new Array()
wid[0] = 103 ; hgt[0] = 100 ; img[0] = new Image()
src[0] = "logo\/mas.gif"
tit[0] = "Local astronomy club&#013;&#010;Dennis Allen webmaster"
url[0] = "http:\/\/"

Note: Make sure to replace any occurrence "/" with "\/" (needed in document.write()).

Note: For external images, add "(x)" to tit[]. Otherwise, this code will wait onload forever.

Finally, add <body onload="logo_init()" onunload="logo_off()">.
