2-Way Background Images SlideShow
Positionable Images or Full Page-Space Display
Functions:
Runs an image slideshow in the background of the page,
underneath the page content. Used with the accompanying
sytle script, images are discretely positionable in the page
space, just like a regular slideshow. Leave out the style
script, and the slideshow runs with full page-space
presentation.
<script language="JavaScript">
// set the following variables
// Set speed (milliseconds)
var speed = 1000
// 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] = 'slideshow1_1.jpg'
Pic[1] = 'slideshow1_2.jpg'
Pic[2] = 'slideshow1_3.jpg'
Pic[3] = 'slideshow1_4.jpg'
Pic[4] = 'slideshow1_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 runBGSlideShow(){
if (document.body){
document.body.background = Pic[j];
j = j + 1
if (j > (p-1)) j=0
t = setTimeout('runBGSlideShow()', speed)
}
}
//-->
</script>
Modify your <body> tag to add the following onload event
<body onload="runBGSlideShow()">
Method One - Positionable Images
----------
Put the following style sheet in the <head> of
your page. Normally it will go *before* the script above.
<style>
body{
background-repeat: no-repeat;
background-position: 200 100;
}
</style>
Set the position x y in pixels in the background-position
element to position the images in the page. Do not use
commas between the values!
Method Two - Full Page-Space Background
----------
Easy - just omit the style script above from the page.
The background images will then repeat across the page, as
usual.
