Random Banners
In my recent re-design on Movalog, I had three banners and unfortunately I liked them all and couldn't figure out which one I liked best. As a result, I decided to use them all.
First I moved all the images to a subfolder called banner and renamed the images to 1.jpg, 2.jpg and 3.jpg. Finally I used PHP's mt_rand function to randomly print a number from 1 to 3 (mt_rand works better than the plain rand function function), like so
<?php echo mt_rand(1,3); ?>
Hence my banner image code looks like this
<?php echo mt_rand(1,3); ?>
<img src="http://www.movalog.com/images/banner/<?php echo mt_rand(1,3); ?>.jpg" alt="Movalog - All Things Movable Type" />

That's cool, but every time I open your site I see just the green banner with the open end wrench on it.
FYI - On my PC, the line of code spills outside your text area so that I can't see the end of the code line. I'm at work using IE 6 on Win 2K with the latest updates.

I have a feeling that your web browser is picking up the cache from the old old stylesheet. Try emptying the cache and trying again. Also I advice you to try another browser like Firefox, Movalog looks very slick in Firefox!
Another thing to note is that the banner doesn't change on every refresh, it may take quite a few refreshes to change.

Hey Arvind, That's pretty cool. I have found though that the rand() function doesn't work very well. Scriptygoddess has posted a fix here that works much better.

OK, now it's working. I didn't realize that they're all green with a wrench. Didn't one of them used to be blue?
I have FF at home, but I actually like Maxthon better, even though it's IE based. Tons of great functionality built in. I learned about it from this article from the Windows Support Center .
Here at work I have no choice, but the IT guy has talked about switching us to FF. I kinda doubt it will happen, though.

Thanks for the heads up Elise, I've updated the tutorial to use the mt_rand() function as opposed to rand()
