A while ago I posted a solution for generating CSS random background images, which provided a PHP server side solution for adding random background images to stylesheets on the fly.
Since it's initial posting the solution provided there has been tweaked and fine tuned based on use and reader feedback. A lot of the feedback and comments were about the inability for readers to use that particular solution because they did not have access to modify the PHP source code. One such example is that of Bloggers, who have access to the Blogger templating system, but not the code.
Comments and feedback are encouraged, as are links from any sites that may find a use for the script!
