thanks lightwave,i will give it a try,do you know if this will work for two images?
This image shows the part of my page with the images i want to change,so maybe that will help answer this question a bit better.The only problem is i dont need a random backround script.I more so want the images to change in a certain order each time the page is refreshed.for example first refresh would make the top image number 1 and bottom image number 1 show,then it would go to top image number 2,bottom image number 2,and so on.
