aiuto PERL resize immagini (thumbs)

[Mez]

Allora, ho un grosso problema non riesco a capire come funziona questa benedetta gallery..

http://eresia-tnt.it/test/ (questo è il mio sito dove ho uplodato la gallery)

http://mig.sourceforge.net/gallery/index.php?currDir=. (questo è la gallery esempio del sito, cioè come la voglio io...)

come faccio a creare delle thumbs con lo script PERL? Devo modificare tramite li i parametri?
lo script è questo:

my $myself = File::Basename::basename($0);      # Program name
my $mydir  = File::Basename::dirname($0);       # Directory $myself lives in
my $myRoot = cwd;                               # Directory I was started in
# Add this to the exec path - easier to find jhead than with relative paths.
# This will not modify the path outside of mkGallery.pl.
$ENV{'PATH'} .= ":$myRoot/$mydir";
my $exifProg = 'jhead';                         # Name of jhead program
my $exifArgs = '';                              # Pass no args to jhead
my $exifFile = 'exif.inf';                      # File to store exif data in
# Defaults for boolean command-line flags
my $allFlag             = 0;        # -a: Process all images
my $exifFlag            = 0;        # -e: Process EXIF data
my $overwriteFlag       = 0;        # -w: Overwrite files instead of append
my $thumbFlag           = 0;        # -t: Create thumbnails
my $commentsFlag        = 0;        # -c: Create comments
my $interactFlag        = 0;        # -i: Interactive mode
my $recurseFlag         = 0;        # -r: Recursion mode
my $newOnlyFlag         = 0;        # -n: Process only new items
my $thumbDirFlag        = 0;        # -d: Use thumbnail subdirectories
my $largeDirFlag        = 0;        # -l: Use large subdirectories
my $keepProfilesFlag    = 0;        # -K: Keep profiles intact
# Defaults for command-line flags which take arguments
my $defaultSize     = 100;          # -s: Thumbnail size
my $defaultQuality  = 50;           # -q: Thumbnail quality
my $defaultMarker   = '';           # -m: Thumbnail label
my $markerType      = '';           # -M: Thumbnail label position
my $defaultThumbDir = 'thumbs';     # -D: Name of thumbnail subdirectory
my $defaultThumbExt = '';           # -E: File extension for thumbnails
my $defaultLargeDir = 'large';      # -L: Name of large subdirectory
# Mode to use for thumbnail subdirectories
my $thumbDirMode    = 0755;

e ho pure un config.php ma questo mi pare di averlo gia settato ok, ma non capisco come funziona sta gallery:

//
// $useThumbSubdir
//     Boolean to turn thumbnail subdirectories on or off.
//     When this is set to TRUE, $markerType and $markerLabel are ignored.
//
// Defaults to TRUE.
//
// Example:
//     $useThumbSubdir = TRUE;
//
$useThumbSubdir = TRUE;
//
// $thumbSubdir
//     What subdirectory to use for thumbnails.  This is ignored if
//     $useThumbSubdir is set to FALSE.
//
// Defaults to "thumbs".
//
// Example:
//     $thumbSubdir = "thumbs";
//
$thumbSubdir = FALSE;
//
// $randomFolderThumbs
//      If TRUE, instead of the generic folder icon, a represenative
//      thumbnail from the folder is shown.  If Mig is unable to find a
//      thumbnail to use, it will use the generic folder icon instead.
//      Unless there are folders whose subfolders and their subfolders
//      and so on have no thumbnails, the generic folder icon should
//      never be used.
//
// Defaults to FALSE.
//
// Example:
//      $randomFolderThumbs = FALSE;
//
$randomFolderThumbs = FALSE;
//
// $useRealRandThumbs
//      If TRUE, a real random selection is done.  It used to be that
//      Mig would just look for the first thumbnail it could find and
//      use that.  A lot of people, including the author, thought that
//      sucked, so $useRealRandThumbs was introduced which will find
//      all available thumbnails and pick one randomly each time the
//      script is called.
//
//      This obviously results in more I/O and on large galleries could
//      cause a problem with execution time.  So I didn't "fix the bug"
//      entirely, I made it an optional behavior.  By default, real
//      random behavior is used, but it can be turned off by setting this
//      to FALSE.
//
//      Generally, you want this to be TRUE unless you have trouble with
//      it (most likely to happen if you have a slow server, a busy server,
//      slow disks, or very large galleries).
//
//      And of course this option is ignored if $randomFolderThumbs is
//      set to FALSE.
//
// Defaults to TRUE.
//
// Example:
//      $useRealRandThumbs = TRUE;
//
$useRealRandThumbs = TRUE;
//
// $useLargeImages
//      Boolean to turn large image support on or off.
//
//      Only turn this feature on if you intend to have three sizes of
//      image - the thumbnail, the regular size version, and a full-size
//      "large" version, such as the original file from the camera.  Most
//      users will want to leave this turned off.
//
//      If set to TRUE, Mig will look for a "large" version of the image
//      in $largeSubdir.  If one is found, a link will be generated
//      pointing to the large image.
//
//      If $largeLinkFromMedium is TRUE, clicking on the medium image
//      will also take the user to the large image.  If you don't want
//      a link printed, but just want to have people click on the medium
//      image only, remove the %%largeLink%% tag from your image.html
//      or mig_image.php template file.
//
//      To use this feature, make sure the following tags are defined in
//      your image.html or mig_image.php template:
//
//          %%largeLink%%       [optional, see above]
//          %%largeHrefStart%%
//          %%largeHrefEnd%%
//          %%largeLinkBorder%%
//
//      Also, copy large.html (or for PHP-Nuke etc, use mig_large.php)
//      to your templates folder.
//
// Defaults to FALSE.
//
// Example:
//      $useLargeImages = FALSE;
//
$useLargeImages = FALSE;
//
// $largeSubdir
//      Name of subdirectory to use for "large" images.  This option is
//      ignored if $useLargeImages is FALSE.
//
// Defaults to "large".
//
// Example:
//      $largeSubdir = "large";
//
$largeSubdir = "large";
//
// $largeLinkFromMedium
//      If TRUE, when viewing a normal image, clicking the image will
//      take you to the large version of the image (if present).
//
//      If FALSE, clicking on the normal image will do nothing, regardless
//      of the presence or absence a large version.
//
//      In either case, if the template tag %%largeLink%% is used, a link
//      to the image will be printed along with the other navigational
//      links on the page.
//
// Defaults to TRUE.
//
// Example:
//      $largeLinkFromMedium = TRUE;
//
$largeLinkFromMedium = TRUE;
//
// $largeLinkUseBorders
//      When $largeLinkFromMedium is TRUE, this setting determines whether
//      to show the link border around a medium image or not.  If TRUE,
//      the border is shown, if FALSE it is not shown.
//
// Defaults to FALSE.
//
// Example:
//      $largeLinkUseBorders = FALSE;
//
$largeLinkUseBorders = FALSE;
//
// $folderNameLength
//      If $randomFolderThumbs is TRUE, folder names will be truncated
//      if they are longer than $folderNameLength characters.  This is
//      done to keep the tables formatted nicely.  This option is ignored
//      if $randomFolderThumbs is FALSE.
//
// Defaults to 15.
//
// Example:
//      $folderNameLength = 15;
//
$folderNameLength = 15;
//
// $markerType
//     Should I use a prefix or a suffix for thumbnails?  This deals with
//     the old way of doing thumbnail naming (i.e. img_4900_th.jpg
//     instead of thumbs/img_4900.jpg).
//
//     Valid values are 'prefix' and 'suffix'.  Ignored if $useThumbSubdir
//     is TRUE.
//
//     If set to 'suffix', thumbnail will be named as in img_4900_th.jpg.
//     If set to 'prefix', it will be named as in th_img_4900.jpg.
//
//     This option is over-ridden by $useThumbSubdir.  Using thumbnail
//     subdirectories is recommended, so avoid this option (along with
//     $markerLabel) if possible.
//
// Defaults to "suffix".
//
// Example:
//     $markerType = "suffix";
//
$markerType = "suffix";

np, risolti, c'è un megabug nello script
