I found this script that lets me resize images on the server and save
the thumbnails in a seperate folder. the only problem is that this
script also generates a bunch of HTML screens which I dont need.
Can someone help me cut the script down to perform the function of
just resizing and saving the images and then displaying a simple HTML
text when finished. It doesnt need to generate web pages to show the
images....
Any help much appreciated:

// Martin's Photo Frame, v3.3
http://dougiamas.com/photoframe
//
// Displays a directory full of images (JPEG, PNG, GIF) simply and
easily.
// It will also create thumbnails and display JPEG comments if it
finds them.
// I am placing this script in the Public Domain - use it as you wish.
//
// Requirements: A web server with this software (note minimum
versions):
// - PHP 4.0.2 http://www.php.net
// - GD 1.8.3 http://www.boutell.com/gd
// - libjpeg 6b ftp://ftp.uu.net/graphics/jpeg/
//
// How to use: 1. Store all your images in a directory on your
server
// 2. Save this file in that directory as index.php
// 3. Make sure the web server has write permissions so
// that it can create a sub directory for thumbnails.
// eg mkdir thumb ; chown nobody thumb
// (optional) 4. Change any of the settings below to suit.
// (optional) 5. Add an intro.html file if you like.
// (optional) 6. Add header.html and footer.html files if you want
// to change page colours, layout or styles.
// (optional) 7. Add a sortfile if you want to control the order
of
// the photos, rather than the default alphabetical
order.
// Just make a simple text file with one filename
per line.
// eg ls -1 .jpg .png > sortfile
// (and then edit with vi)
//

// Default Settings - change here or create a config.php that
overrides them
// If using a config.php make sure you put PHP tags around the lines
of code

$marginsize = 150; // Size of left-hand frame with
thumbnails
$pagecolor = "#FFFFFF"; // Default background color of
pages
$textcolor = "#000000"; // Default text color for all
pages
$imagesize = false; // Resize images to fit window?
true/false
$thumb = "./thumb"; // Directory where thumbnails are
stored
$getcomment = "/usr/bin/rdjpgcom"; // To extract JPG comments (part
of libjpeg)
$introfile = "intro.html"; // If it exists, will be
displayed up front
$headerfile = "header.html"; // If it exists, will be included
at top
