Random image rotator

[Stupot_]

EDIT: I just tried this in internet explorer, opera and firefox and it works (I'm using chrome). How can I make it work better in chrome? (I've cleared my cache etc...)


Ok this is doing my nut in! Any help would be appreciated!

This is my site:

www.stuartcuss.co.uk

I'd like the vertical banner on the right to cycle through a bunch of images when you hit refresh. Currently it's not working, it's just sticking on one image.

I have a folder with the images in and this php file. Apparently I just need to put the php file in the same folder as the images and change some stuff, then link to it with an img src script.

PHP File:

<?
/*/////////////////////////////////////////////////////////////////////////////////////////
Created by: Mr_density

Description:
A simple random image generator.
I wrote this script because i had some trouble with other similar scripts that didn't work
as well as this one.

Instructions:
1. Just put this script in the directory containing your images and connect via a
browser to this script. The script wil only show images (jpg, gif, png) not other
file formats.

2. Via an html image tag your can call the script on your site.
syntax: <img src="randompic.php"> or <img src="randompic.php?tnsize=XXX"> (to resize).

Change $config["systempath"] to the path where the images are stored (not the URL and no slash on the end). 
Change $config["webpath"] to the path where the images can be found through a webbrowser (include a ending slash).

The options for $config["type"] are "redirect" and "readfile". Redirect will use a "location" header wich will display the image (kind of redirect so). Readfile will read the file from the local hardrive and directly displayed (actually I can not recommend that).
////////////////////////////////////////////////////////////////////////////////////////*/
$config["images/randomheader"]	= "";
$config["http://www.stuartcuss.co.uk/images/"]		= "";
$config["redirect"]			= "redirect";

if($config["images/randomheader"] != "")
{
    $dircheck = $config["images/randomheader"];
    if (is_dir($dircheck)) //check if it is a valid systempath
    {
		$pathtoread = $config["images/randomheader"];
	}
	else
	{
		 // If not, it creates an error image and displays it
		 $img = imagecreate(150, 150);
		 $red = imagecolorallocate($img, 255, 0, 0);
		 $yellow = imagecolorallocate($img, 255,255, 0);

closedir ($imgdir); 

// Removes all non-image files
$tempvar = 0;
for ($i = 0; $images[$i]; $i++)
{
	$ext = strtolower(substr($images[$i],-4));

The site uses a CMS called indexhibit, there is a box which I can change which displays the banner. This is how I've linked to the php file:

Finally, the css for the site is here if that helps!

What happened to the $config[] array in the php file? You've replaced the keys and not assigned any value to them.
