Javascript is a means to provide an interactive web application. Simple examples are replacing images. More complex ones are changing the entire layout of the application. Move things around. Send and receive information in the background to and from the server as well as provide interactive feed back to the end-users. If you want to see what javascript can do when used to the max check out www.meebo.com their entire service is created using javascript and a technology known as AJAX

You could do this:
<script Language="JavaScript">
tips = new Array(Y)
tips[0] = "<img src=..X>"
tips[1] = "<img src=..X>"
tips[2] = "<img src=..X>"
index = Math.floor(Math.random() * tips.length)
document.write("<center>" + tips[index] + "</center><p>")
</script>
Where X defnes the different images (changing each time) you can add more by simply adding another line
E.G: in this case the next image would be:
tips[3] = "<img src=..X>"
in the same way as you can remove them by simply deleting the unrequired text.
But remember the Y command must define how many you have, in this caase 3.
Hope his helps :D

That function is called a Random Image function. Below is a link to a site which has the code -it needs to be pasted into your HTML page and customized for the pics you are using for the function.
