Loading a background image from array
I have coded in html/php/css, but have not done anything too elaborate. I was looking at a site that had a different image every time on reload. When looking at the source code for the site, I found the following code that was placing the background.
On every reload the "bg002.jpg" portion of the code would change. Can anyone explain a method or script that could be causing this? There is no other code on the page that would refer to an array that the background images are being caller from.
Many thanks in advance!!
