1) Script Title: Fade-in image slideshow

2) Script URL (on DD): Not sure on DD, because I found the script originally on another site, but thanks to the credit I was able to find you. Here it is on my Web design:

<script language="JavaScript1.2">
//Fade-in image slideshow- By Dynamic Drive

var slideshow_width='723px' //SET IMAGE WIDTH
var slideshow_height='226px' //SET IMAGE HEIGHT
var pause=3000 //SET PAUSE BETWEEN SLIDE (3000=3 seconds)

var fadeimages=new Array()
//SET IMAGE PATHS. Extend or contract array as needed

3) Describe problem:
Not a problem/error but a basic question about linking/anchoring and JavaScript.

I want to make the image slideshow link to a page within the site, but the usual A tags don't seem to be doing it the trick. I take it you cannot put an A tag around a JavaScript and have it work in the same way as if it were wrapped around text or an image. (A) Is there an additional javascript that I can add to the page to make the slideshow link? And---here's the kicker--- (B) is it possibe to make each image link to a different place? For example, if one slide talks about the new location, and the next talks about a new product, and a third talks about a download... if we could make each slide link off to another place, that would be huge.

By the way, the slideshow looks phenomenal. I am very pleased. Thank you so so much for sharing your expertise.

Best,
Barry

This script has been replaced by:

Ultimate Fade-in slide show (v1.5) (http://www.dynamicdrive.com/dynamicindex14/fadeinslideshow.htm)

which has an option for links for each image.
