HOW TO DECLARE A NEW SLIDESHOW IN THE HTML:
new fadeshow(IMAGES_ARRAY_NAME, slideshow_width, slideshow_height, borderwidth, delay, pause, optionalRandomOrder)

   1. IMAGES_ARRAY_NAME: The name of the image array (inside script of Step 1) containing the images to display for this slideshow (ie: "fadeimages".
   2. slideshow_width: The width of the slideshow container (implied in px). Set it to accommodate the largest image within the slideshow.
   3. slideshow_height: The height of the slideshow container (implied in px). Set it to accommodate the largest image within the slideshow.
   4. borderwidth: The width of the border, such as 0, 1 etc.
   5. delay: Delay between image change, in milliseconds (ie: 3000 = 3 seconds).
   6. pause: Specify whether slideshow should pause (not rotate) while the mouse is over it. 1=yes, 0=no.
   7. optionalRandomOrder: An optional parameter specifying whether to "randomize" the display order of the images. Set it to "R" to randomize, or remove this parameter (unset) to not.

As mentioned, you can invoke "fadeshow()" multiple times on the same page to display multiple fade in slideshows. Fade away we say!
