Randoam Images On Page Reload or Refresh!

Ok with a little help from a coder over at www.dynamicdrive.com I have made a serious improvement to this mod.

You can now have random multiple images fall on every page refresh. Meaning each time the page is refreshed of changed a different image will fall! The images can even be animated gifs to create a serious effect for your site.

Here is the new code for you all! Just change the path and list for the images highlighted in Red.

Here is a live demo: Live Example

HAPPY HOLIDAYS!
