different image everytime page is refreshed

I found this site: http://www.carltonward.com
Everytime the index page is refreshed, a different image pops up.
I'm not proficient with code yet, and I was wondering if someone could help me
figure out how to make this happen.
What code is being used and where should it be placed?

Thanks for your time...

You could store all your images in a directory and name them 1,2,3,4,5. Then
use your scriptin language to generate a random number.

In PHP this would look something like:

<img src="images/<? echo rand(1, 5); ?>.jpg">

if you want it easy and to use client-side javascript, visit
http://kaosweaver.com and get the free random image extension or the
advanced commercial version.

and- it's a good idea to put in <noscript><img
src="oneoftheimages.jpg"></noscript>

so that an image will load for those with JS turned off.

In PHP this would look something like:

img src="images/<? echo rand(1, 5); ?>.jpg"

OK, but:

If you want your code be reliable and portable you should avoid short
open tags and use the correct <?php ... ?> instead. Short open tags
could be disabled on some machines and are a problem if you use XML.

Thanks for the feedback.
Two questions for you:

1. Where exactly should I insert that code snippet (<noscript><img
src="oneoftheimages.jpg"></noscript>) ?

2. How would one go about turning their java script on and off?

Thanks again!

Hi Micha,

Thanks I didn't know that, how about using this format for inserting code
into HTML <?=$myVar?>

It's the same, it's a short tag (same as <? echo $myVar?>). As said
before - this may be convenient, but could be disabled in the server
configuration. And if you want to output an XML prolog somewhere (for
example in an XHTML document with embedded PHP code) ...

<?xml version="..." encoding="...">

.... you're in trouble because PHP interprets the <? as its own start
tag, which will cause a parse error in the code above.

There are some comments and recommendations in the manual:

Escaping from HTML
http://www.php.net/manual/en/language.basic-syntax.php#language.basic-syntax.phpmode

short_open_tag
http://www.php.net/manual/en/ini.sect.language-options.php#ini.short-open-tag

Quote:
"Using short tags should be avoided when developing applications or
libraries that are meant for redistribution, or deployment on PHP
servers which are not under your control, because short tags may not be
supported on the target server. For portable, redistributable code, be
sure not to use short tags."
