Galerie - Změna složky

Na webu jsem našel tuto galerii, ale rád bych ji změnil tak, aby bylo možné obrázky ukládat do podsložky.

# Set the following configuration variables if you don't#
# want to use the defaults. We suggest giving the script#
# a test-run with the defaults to see how it looks, then#
# deleting the auto generated thumbnails and making any #
# desired changes to the settings. When you load up the #
# script again, new thumbs will be generated. #

# Path to HTML template which contains the %output% token, if you
# want to use your own template. Defaults to built-in template.
# If you create your own, just stick %output% in the HTML file
# wherever you want the gallery output to appear.

# Here are the width and height settings for thumbnails. In most
# cases you will want to specify a value for one of these, and set
# the other one to 0, this enables the auto ratio calculations.
# If you set both to nonzero values, your thumbnails will all
# be generated at the exact same height/width but they'll end up
# looking "warped" and out of proportion. You MUST set at least
# one, either the height or the width.

# Desired width of thumbnails (or 0 for auto)
$thumbw = 100;

# Desired height of thumbnails (or 0 for auto)
$thumbh = 0;

# The thumbnails will be displayed in a table. The following
# variables control the appearance of the table.

# $perrow = number of thumbnails to display in each row
$perrow = 2;

# $perpage = number of images to display per page, this
# really should be some multiple of $perrow
$perpage = 8;

# Size of the border for the table, in pixels
$tableborder = 0;

# Width of the table
$tablewidth = "75%";

# Cell spacing for the table, in pixels
$cellspacing = 3;

# Color of the table
$bgcolor = "#67378B";

# Font to use for displaying the table
$fontface = "Verdana, Arial";

# Font size
$fontsize = 2;

# You can have information about each image displayed below
# its thumbnail in the table. Use the following settings to
# toggle these displays on or off by setting to 1 or 0.

# Display file name
$showname = 1;

# Display image coordinates
$showcoords = 0;

# Display file size in KB
$showsize = 1;

# If you want PHP to include() a header before displaying
# the gallery page, set the full system path here, e.g.
# /home/foo/public_html/gallery/header.php
$header = '';

# If you want PHP to include() a footer after displaying
# the gallery page, set the full system path here, e.g.
# /home/foo/public_html/gallery/footer.php
$footer = '';

# By default, thumbnails displayed in the gallery will link
# directly to the fullsize JPG. If you'd rather have them
# point somewhere else (for example to your own script that
# checks a user's cookie or tracks how many times each pic
# has been viewed), you can take advantage of the $linkurl
# variable. The %picname% token will be replaced automatically.
# For example you might want the thumbnails to link to
# "/your/site/viewpic.php?image=%picname%" where viewpic.php
# is a script you wrote that counts the view and displays the
# image specified by %picname%
# If you do not need this capability, leave the default
# value, the default will work for most people.

$linkurl = "%picname%";
