This script is intended to be used as a Halloween script but you can use any image you like for the "Ghosts".
To add an image to the page animation simply add the code
JSFX.AddGhost ("<IMG SRC='YOUR_IMAGE.gif'>");
Where <IMG SRC='YOUR_IMAGE.gif'> is the valid HTML that defines the image you want to display (See the source code of this page)
NOTE: The images available
with this demo are provided with the example script because as far as I am aware
they are royalty free.
You can probably obtain more images either by visiting the resources
or by searching the web
