Having images change on your web site is a slick way to give the impression of freshness to your site for a returning visitor.
This simple PHP script will display a random image from all the images available to it.
Reload this page to see the random image changer in action.
Using this script on your site.
I use simple scripts like this as custom functions included in the head of my web page. Then, I can call the function without a lot of extra markup involved. Keeps my pages leaner and cleaner.
So, for this example, I would save the php code as a page called 'randomImage.inc.php' and put it in a folder I call 'includes'.
Remember, you'll have to save your web page with the '.php' extension to get the script to work!
