This is page of plugin http://www.robwalshonline.com/posts/jquery-plugin-random-image-on-page-load/

How to get this work in all browser FF, safari, chrome and IE 6, 7 ,8

Answer 1

Putting a comma after the last element of a list or object literal works in FF but is invalid in IE:

myImages: ['image1.jpg', 'image2.jpg', 'image3.jpg', 'image4.jpg', 'image5.jpg', ] //put image names in this bracket. ex: 'harold.jpg', 'maude.jpg', 'etc'

Consequently winnerImage will be undefined in IE, and it will try to load the image at http://www.robwalshonline.com/demos/randomImageDemo/images/undefined
