ALA - A better image rotator
http://www.alistapart.com/articles/betterrotator/
I'm trying to get a random header going on my latest project, http://madclassifieds.000k.net/zap/ (html version)
The php version (which won't display) is at http://madclassifieds.000k.net/zap/index.php
When you go there (as you can see) it says cannot read ini file
the ini is at http://madclassifieds.000k.net/zap/imgs/headers/headers.ini
and the rotator script is at http://madclassifieds.000k.net/zap/imgs/headers/rotate.php

It would be nice to see the PHP code, not just a link to the file.
If you're on Apache you might try saving copies of your .php files with the extension .phps. You can link to these files, and they'll display with syntax highlighting and all.
I'm guessing you have a path or permission problem. Let's see the code and file vitals.

Try using an internal path to the file rather than a http url.

This is a very simple method I use for displaying random images
<?php
function randImage() {
\\ 3 is the number of images I have starting at 0
$number = rand(0,3);
\\ path to images
echo "<img src=\"images/image" . $number . ".png\">";
}
?>
Just call the function from where you want the image to display, remember they must all be named correctly (image0.png, image1.png etc)
There are no stupid questions, only stupid people!
