Greetings,
I'm not a very advanced programmer at all.
I found a piece of code that helps me out a lot at http://www.codelifter.com/main/javascript/slideshow2.html. It allows an image to crossfade into another, into another, etc.
I'd like to be able to crossfade an image, with a text caption underneath it, to crossfade into a different image with different text, into another, etc.
I think doing this may have something to do with putting the image and caption into a <div>, and then changing the code to swap the first <div> into the next, into the next.
The code identifies the images as 1.jpg, 2.jpg, 3.jpg, etc. It would be awesome if the captions could come from 1.txt, 2.txt, 3.txt, etc.
If Javascript can't call up .txt files, then the captions could be put inside the current web page into a table that is set to be hidden (display: none).
Can anyone help me do this?
The reason I want to use Javascript is because I do not wish to use anything that will make visitors have to have additional software (like Java or Flash). Additionally, it is not a problem if they have Javascrpt disabled, because then they'll just see the first image with the first caption, which is fine. I can't use anything like PHP or PERL because I have very little control over the server.
Thank you very much.

Here is the original code:
==========================================================
Script: JavaScript Cross-Browser SlideShow Script
With Cross-Fade Effect between Images
Adjustable Timing and Unlimited Images
Function: Displays images continuously in a slideshow
presentation format, with a fade effect on
image transitions.
Browsers: All common browsers: NS3-6, IE 4-6
Fade effect only in IE; others degrade gracefully
Author: etLux
==========================================================
Step 1.
Put the following script in the head of your page:
<script>
// (C) 2000 www.CodeLifter.com
// http://www.codelifter.com
// Free for all users, but leave in this header
// NS4-6,IE4-6
// Fade effect only in IE; degrades gracefully
// =======================================
// set the following variables
// =======================================
// Set slideShowSpeed (milliseconds)
var slideShowSpeed = 5000
// Duration of crossfade (seconds)
var crossFadeDuration = 3
// Specify the image files
var Pic = new Array() // don't touch this
// to add more images, just continue
// the pattern, adding to the array below
Pic[0] = '1.jpg'
Pic[1] = '2.jpg'
Pic[2] = '3.jpg'
Pic[3] = '4.jpg'
Pic[4] = '5.jpg'
// =======================================
// do not edit anything below this line
// =======================================
var t
var j = 0
var p = Pic.length
var preLoad = new Array()
for (i = 0; i < p; i++){
preLoad[i] = new Image()
preLoad[i].src = Pic[i]
}
function runSlideShow(){
if (document.all){
document.images.SlideShow.style.filter="blendTrans(duration=2)"
document.images.SlideShow.style.filter="blendTrans(duration=crossFadeDuration)"
document.images.SlideShow.filters.blendTrans.Apply()
}
document.images.SlideShow.src = preLoad[j].src
if (document.all){
document.images.SlideShow.filters.blendTrans.Play()
}
j = j + 1
if (j > (p-1)) j=0
t = setTimeout('runSlideShow()', slideShowSpeed)
}
</script>
==========================================================
Step 2.
Put this onload event call in your body tag:
<body onload="runSlideShow()">
==========================================================
Step 3.
Put this in the body of your page where you want the
slide show to appear.
Set widths and heights same as images
Set image file same as first image in array Pic[] (above)
<table border="0" cellpadding="0" cellspacing="0">
<tr>
<td id="VU" height=150 width=150>
<img src="1.jpg" name='SlideShow' width=150 height=150></td>
</tr>
</table>
