A while back I wanted to show some images on this blog - but have the ability to randomly select an image to show. I wanted it to be as "hands off" as possible, so here's the code I came up with;

$idea_images = glob("ideasfestival*.gif");
shuffle($idea_images);
echo '<a xhref="http://www.ideasfestival.org"><img border="0" xsrc="http://www.osworld.biz/', $idea_images[0], '" /></a>';

Basically, this code puts all the images that start with "ideasfestival" into an array. It then shuffles the array and outputs the first image selected.

If you want to use this code, you'll need to change it a bit, here's how;

1. Change the link url - simply change the http://www.ideasfestival.org to your own URL link
2. Change the first "glob" line from ideasfestival to aaa (or somesuch)
3. Make sure that all your images that you want to rotate start with "aaa" (or whatever you changed the previous step to).

This is a nice easy, hands off way to make an image "rotator" - when you want to add more images, simply make sure that their name starts with "aaa" and upload it. Easy as 123.

Have fun!
