// PHP webcomic update script v. 2.1 by Jim Newberry with lots
// of help from Doug Shepherd's excellent article, located here:
// http://www.webtools.com/story/scripting/TLS20000421S0001
//
// Yes, I'm aware the article is no longer available. But I gotta
// give credit where it's due... so the link remains until I locate
// another version of the article :)

// The following variables must be customized as indicated.

// Absolute path to your comic image files. Don't include a "/" on the end. This value
// is not a URL (http://...). It is the location of your website files on your host server.
// If you don't know it, ask your host or consult their FAQ.
    $comic_path = "/home/sites/www.paint-zone.co.uk/web";

// This is the relative URL of your comic image files. If this file is located at
// http://www.yoursite.com/index.php, and your comics are in the http://www.yoursite.com/strips
// directory, then the URL would be "strips". This value can be EITHER relative (as the example
// shows, or a full HTTP address: "http://www.yoursite.com/strips".

// This means all your comic files must be the same extension.

// This variable indicates whether or not you want the script to display comic images.
// In other words, you could just put your strips in .html files and have the script
// pull them that way. IMPORTANT: Either $strips or $news MUST be "yes" or you won't
// see either. They can BOTH be "yes" if you want.

// me debug the problem where the most recent comic displays twice if its filename
