Help with ImageMagic module

[mellin]

I was reading the ImageMagic.org website, and tried to make a sample script to automatically resize pictures, from given folder. Then to save those resized pictures to another directory, thus saving me from the work to make thumbnails each time i add a new picture to my site.

Anyway, it really wasn't that simple. Once i started to wrote the script, i didn't anymore understand anything i just read!

This is where i got, actually nowhere but..

-----------------------------------------------------------------------
#!/usr/bin/perl

use CGI;
use Image::Magick;

$query = new CGI;

@imgdir = ("sarah.jpg", "eliza.jpg", "alyson.jpg", "charisma.jpg", "amber.jpg");

$cgi-dir = "/var/www/cgi-bin";
$cgi-lib.pl = "cgi-lib.pl";
$variables.lib = "variables.lib";

require "$cgi-dir/$cgi-lib.pl";
require "$cgi-dir/$variables.lib";

what_to_do();

what_to_do {

build_page() if $q eq "";
show_the_image() if $img;
}

sub build_page {

for (@imgdir) {

$image = Image::Magick->new;
open (IMAGE, "$_")|| &error;
$image->Read(file=>\*IMAGE);
close (IMAGE);
}
}

sub show_the_image {

}

sub error {

print "<p>$error</p>";
}
-----------------------------------------------------------------------

How do i actually tell the imagemagic, what image to resize, what name to use to that new image, and most importantly, what size to resize it to?

Once i understand how to open an image, resize it, save it, i'll be where i want. I think.
