Full screen random background images on a website

As mentioned above the challenge is to have full screen background images on a webpage. The images should be chosen from a pool of images randomly. Everything needs to be browser independent. There should not be some CSS3 because IE does not handle CSS3 well enough at that time.

Full screen random background images using Supersized (javaScript)

In order to have full screen background images on a website you may consider using a jQuery plug in named Supersized. Supersized is available from http://buildinternet.com/project/supersized/ under the GPL and MIT License.

To get supersized to work properly on a website you have to include some JavaScript and CSS in the head section of your html site.

1. the jQuery plugin
script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.5.0/jquery.min.js"/>

2. the supersized plugin (which you downloaded from the website shown in the first paragraph)
script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.5.0/jquery.min.js"/>

3. the CSS file that comes with the supersized zip from the download
link rel="stylesheet" href="css/supersized.css" type="text/css" media="screen" />

After including these script and CSS files you can either make a separate javaScript file and include it as well or just use the fallowing code within the head tags of the site you want to use supersized on.

script type="text/javascript">

Looking at the javaScript we can see that there is the possibility to set the start slide variable to "0". As a result the fullscreen background slideshow starts with a random image.
As we can see at the variables above there is a great number of possibilities to tweak the appearance of the background slideshow.
