/*
* Modified by Jake Nicholson (www.eskdale.net) 22nd July 2010 to show multiple images on slider in a row without jumping around when the slider repeats itself.
* To use this, set option "showMultiple" to "true" in the tag thusly:
*
*
*
*
*
*
*
*
*
* "showCount" sets the width of ul. At some point it will be more important.
* Repeat all images once to avoid glitches with loop, the JS will take care of the rest.
* I made a bunch of changes to the CSS as well, so you may need to get take a look at "screen.css" to get it working properly
*
* Oh yeah, and there's a fade effect on any images placed in the element if you want it.
* (Set fadeImage: true,)
*
* This is still a work in progress....
