$('div#rotator ul li').css({opacity: 0.0});
//Get the first image and display it (gets set to full opacity)
$('div#rotator ul li:first').css({opacity: 1.0});
//Call the rotator function to run the slideshow, 6000 = change to next image after 6 seconds
setInterval('rotate()',6000);
}
function rotate() {
//Get the first image
var current = ($('div#rotator ul li.show')? $('div#rotator ul li.show') : $('div#rotator ul li:first'));
//Get next image, when it reaches the end, rotate it back to the first image
var next = ((current.next().length) ? ((current.next().hasClass('show')) ? $('div#rotator ul li:first') :current.next()) : $('div#rotator ul li:first'));
//Set the fade in effect for the next image, the show class has higher z-index

/* ********************************************************************
* HTML Block Scroller & Marquee JavaScript - v2.0
* - Copyright 2008 - Licenced for free distribution under the BSDL
* - http://www.opensource.org/licenses/bsd-license.php
*
* Have one or more scrolling blocks of HTML anywhere on your webpages.
* The scroller will even pause on mouseover and resume on mouseout.
*
* Version 2.0
* - Uses DOM-only methods (compatible with application/xhtml+xml)
* - Blocks are created in the HTML page, rather than as JS variables
* - Automatic startup on page load
***********************************************************************
*** Instructions ******************************************************
***********************************************************************
* 1. Create the container for the scroller in the body of your HTML:
*
* <div id="scr1"></div>
*
* Where "scr1" is any name you choose. You don't have to use a <div>
* either. You may use any block level element that can be pixel
* resized; such as a <span> element to which the display:block; CSS
* property has been applied.
*
***********************************************************************
* 2. Fill the scroller container with child <div> blocks:
*
* <div id="scr1">
* <div class="default">
* The contents of this block will be displayed if the browser does
* not support the scroller.
* It will be overwritten if the scroller is supported.
* </div>
* <div>Block 2</div>
* <div>Block 3</div>
*
* ...
*
* </div>
*
* Assign the class "default" to the first block, the one which you
* would like displayed if javascript is disabled.
*
***********************************************************************
* 3. Add the following rule(s) to your CSS stylesheet:
*
* #scr1 div {
* visibility:hidden;
* }
* #scr1, #scr1 div.default {
* width:160px;
* height:120px;
* overflow:hidden;
* visibility:visible;
* }
* #scr1 table tr td div {
* visibility:visible;
* }
*
* Change both "scr1" to the id you gave to the scroller container. The
* width and height properties should match those you will use in step 4.
*
* To further style the scroller container, assign CSS properties to the
* scroller target id:
*
* #scr1 {
* background-color:#f6f6f6;
* margin:0px auto;
* }
*
* The script will replace each block you add to the container with a
* single-celled <table>. So to style the blocks of your scroller, you
* can style these table cells as if they were actually part of your
* document source:
*
* #scr1 table tr td {
* padding:10px;
* color:#ff0000;
* text-align:center;
* vertical-align:middle;
* }
*
***********************************************************************
* 4. Create a new scrollObject:
*
* new scrollObject("scr1", 120, 120, "up", 5000, 1.4);
*
* The arguments for this object are as follows:
* a. - ID of the target tag (from step 1)
* b. - Width (in pixels) of your scroller
* c. - Height (in pixels) of your scroller
* d. - Scroll direction: one of "up", "down", "left" or "right"
* e. - Amount of time to pause before next scroll begins (ms)
* f. - Slide-in speed of your scroller (1.001 up to width or height)
*
***********************************************************************
*** To add more scrollers to the same page: ***************************
***********************************************************************
* 1. Create additional containers - with different ID's - and blocks in
* the body of your HTML
*
* <div id="scr2">
* <div class="default"><strong>HTML is allowed too!</strong></div>
* <div><img src="/images/mybanner.jpg" alt=""></div>
* <div><a href="/home">And links!</a></div>
* <div>As long as it fits within the dimensions above</div>
* </div>
*
* <div id="scr3">
* <div class="default">Block 1</div>
* <div>Block 2</div>
* <div>Block 3</div>
* <div>Block 4</div>
* </div>
*
***********************************************************************
* 2. Add the matching rules to your CSS stylesheet
*
* #scr2 div,
* #scr3 div {
* visibility:hidden;
* }
* #scr2, #scr2 div.default {
* width:468px;
* height:60px;
* overflow:hidden;
* visibility:visible;
* }
* #scr3, #scr3 div.default {
* width:140px;
* height:140px;
* overflow:hidden;
* visibility:visible;
* }
* #scr2 table tr td div,
* #scr3 table tr td div {
* visibility:visible;
* }
*
***********************************************************************
* 3. Create new scrollObjects for each scroller in the <script> tag:
*
* new scrollObject("scr2", 468, 60, "down", 10000, 1.2);
* new scrollObject("scr3", 140, 140, "right", 4000, 2);
*
***********************************************************************
