       lazygal - static web gallery generator


       lazygal [-h | -v | [options] albumdir]


       This manual page explains the lazygal program. This program is a static web gallery
       generator written in Python.

       lazygal works so: you should have an original store of files - possibly containg
       subdirectories (their names serving as headings if not using the album metadata feature).
       This is the source file hierarchy. It will never be modified by lazygal. Then, when

       $ lazygal -o /var/www/MyAlbum /home/user/SourceDir

       lazygal will analyze the contents of the source hierarchy and will (re)create the target
       hierarchy, with all the bells and whistles defined by the templates. Only missing parts or
       parts that are not up to date will be generated. There is a limitation to this mechanism
       though: although updates in the source directory, in the metadata or in the themes are
       detected, changes in command line options and configuration files since last generation
       are not and the user should manually delete files that need to be generated again.


       These programs follow the usual GNU command line syntax, with long options starting with
       two dashes (`-'). A summary of options is included below. For a complete description, see
       the -h switch.

       -v --version
           Show program's version number and exit.

       -h --help
           Show summary of options.

           Don't output anything except for errors.

           Output everything that lazygal is doing.

       -o DEST_DIR --output-directory=DEST_DIR
           Directory where web pages, slides and thumbs will be written (default is current

       -t THEME --theme=THEME
           Theme name (looked up in theme directory) or theme full path.

           Default style to apply to the theme.

           Common variables to load all templates with, e.g.  --template-vars='footer=foo
           bar,color=baz'. For longer variable contents, it is easier to use a configuration file
           (see lazygal.conf(5)).

       -f --force-gen-pages
           Force rebuild of web pages, regardless of the modification times of their
           dependencies. This is handy when changing a configuration option affecting these
           (theme, directory flattening, etc.).

           Clean destination directory of files that should not be there.

           Specify a file pattern (or name) which should be ignored during cleanup of the
           destination. May be specified more than once. Values given here will be in addition to
           those specified in configuration files.

           Specify a file pattern (or name) which should be ignored during processing. May be
           specified more than once. Values given here will be in addition to those specified in
           configuration files.

           Exhaustively go through all directories regardless of source modification time.

       -s IMAGE_SIZE --image-size=IMAGE_SIZE
           Size of images, define as name=xxy, ..., eg. small=800x600,medium=1024x768. The
           special dimensions 0x0 use original size. Refer to the IMAGE RESIZE DESCRIPTION
           section for more information on the available syntax.

       -T THUMBNAIL_SIZE --thumbnail-size=THUMBNAIL_SIZE
           Size of thumbnails, eg. 150x113. Refer to the IMAGE RESIZE DESCRIPTION section for
           more information on the available syntax.

       -q QUALITY --quality=QUALITY
           Quality of generated JPEG images (default is 85).

       -O --original
           Include original photos in output.

           Do not copy original photos in output directory, instead link them using RELATIVE_PATH
           as base for those links (discarded without -O).

           Do not copy original photos in output directory, instead create symlinks to their
           original locations. This is useful when you plan transferring the whole directory
           which lazygal generated to some other location, perhaps with rsync, and you wish to
           avoid creating an extra copy of each photo.

               This option is not available on Windows; if you try to use it on that operating
               system, lazygal will immediately exit with an exit status of 1.

           Publication URL (only useful for feed generation).

       -m --generate-metadata
           Generate metadata description files where they don't exist in the source tree instead
           of generating the web gallery. This disables all other options.

       -n THUMBS_PER_PAGE --thumbs-per-page=THUMBS_PER_PAGE
           Maximum number of thumbs per index page. This enables index pagination (0 is

           If set, lazygal will only export the pictures that have one of their (IPTC) tags
           matching TAG. It is also possible to use an equivalent of AND and OR boolean tests to
           filter tags. For more details, read below the section TAG FILTERING.

           Sort order for images in a subgallery, among 'mtime', 'filename', 'numeric', or
           'exif'. (default is 'exif' which is by EXIF date if EXIF data is available, filename
           otherwise, sorting EXIF-less images before). 'numeric' does a numeric sort on the
           numeric part of the filename. Add ':reverse' to reverse the sort order (e.g.

           Sort order for subgalleries, among 'exif' (EXIF date of the latest picture in
           sub-gallery), 'mtime', 'dirname', or 'numeric' (default is 'dirname'). 'numeric' does
           a numeric sort on the numeric part of the dirname. Add ':reverse' to reverse the sort
           order (e.g.  --subgal-sort-by=dirname:reverse).

           Level below which the directory tree is flattened. Default is no flattening ('No').

           This option makes the program include the web gallery index of child galleries in
           their parent's gallery index, if their level is greater than the supplied LEVEL. The
           level of the album root is 0.

           Index pages with multiple galleries (which happens when this section is used) show the
           pictures links in gallery sections.

           The following examples show the produced indexes for a sample album (2 sub-galleries,
           1 sub-sub-gallery, 1 picture in each one of those).

           Example 1. --dir-flattening-depth=No (default)

                             index.html <- sub-gallery links
                             subgal1/index.html <- index with img1
                             subgal1/subsubgal1/index.html <- index with img2
                             subgal2/index.html <- index with img3

           Example 2. --dir-flattening-depth=0

                             index.html <- contains index for all pics

           Example 3. --dir-flattening-depth=1

                             index.html <- contains index for all pics
                             subgal1/index.html <- index with img1 and img2
                             subgal2/index.html <- index with img3

       -z --make-dir-zip
           Make a zip archive of original pictures for each directory.

           Webalbum picture background color. Default is transparent, and implies the PNG format.
           Any other value, e.g. red, white, blue, uses JPEG.

           What type of web album thumbnails to generate. By default, lazygal generates the
           well-loved "messy" thumbnails with randomly selected pictures from the album each
           rotated by a random amount and pasted together. This default can also be forced by
           specifying 'messy' as WEBALBUMPIC_TYPE.

           On the other hand, specifying 'tidy' as the value of this option forces lazygal to
           skip the rotations, resulting in more regularly shaped thumbnails which can also be
           more densely packed. This can be an advantage if not all users of your albums have
           huge screens :-)

           Do not remove GPS data from EXIF tags. By default the location tags are removed for
           privacy reasons. However, there are situations when having the location data makes
           sense and is desired. This is mostly meant to be used with holiday photos.


       A theme maps to a directory that contains the following items:

           Files to put in the web gallery shared directory, e.g. CSS, Javascript, images or
           other resources common to all galleries.

           The XHTML template for the theme browse page (displaying one picture).

       theme/dirindex.thtml or theme/dynindex.thtml
           The XHTML template for the directory index page (pictures and sub-galleries links).

       Depending on which index file is present, the theme will be:

       dirindex.thtml: fully static
           one HTML page per picture, per size and one index per size, or

       dynindex.thtml: dynamic
           only one index per directory is to be generated.

       theme/*.thtml must be valid XML. See for syntax. Dependencies
       for statically included templates (i.e. with filenames not computed from variables) are
       automatically computed: when an included template is modified, the software will
       automatically figure out which pages to re-generate. Missing template files will be
       searched for in the default theme.

       theme/SHARED_* files (common resources for the shared directory) are renamed to strip the
       SHARED_ prefix and:

       •   Processed using the Genshi text template engine (see
  for syntax.) if
           their file extension starts with t,

       •   Copied to the web album destination otherwise.

       Using the theme manifest theme/manifest.json file, it is possible to include files from
       other directories to be copied into the web album shared files.

       Example 4. manifest.json

               "shared": [
                   # copy as shared/lib.js
                   { "path": "../lib-2.1.js", "dest": "lib.js" },

                   # copy as shared/js/lib-2.1.js
                   { "path": "../lib-2.1.js", "dest": "js/" }

       Please refer to the examples supplied in /usr/share/lazygal/themes.


       If a directory from the source album contains a file named album_description, it is
       processed as a source of album metadata. The format is borrowed from another album
       generating tool - Matew. Each line is treated as one possible tag, unknown lines are
       simply ignored. Example content of this file follows:

       Example 5. album_description

           Album name "My album"
           Album description "Description, which can be very long."
           Album image identifier relative/path/to/image.jpg

       Otherwise, the user can provide metadata in the following files.

           The title to use for this album directory.

           The description for this album directory. HTML tags are used verbatim from this file.

           The relative path to the image to use at the top of the album picture stack.

           The description to use for this particular image. Please note that HTML tags are taken
           as provided in this file for output in the templates.

       Lazygal also extracts information from many metadata tags in image files. Regarding image
       description, Lazygal searches for comments in this order:

        1. pic.jpeg.comment file

        2. Exif.Photo.UserComment

        3. Exif.Image.ImageDescription

        4. Iptc.Application2.ObjectName

        5. JPEG comment


           User configuration directory.

           User themes directory.


       Multiple configuration files are processed by lazygal. The configuration is initially set
       up with the defaults. The defaults can be found in the lazygal source distribution in

       Then, the configuration files are processed in the following order, each newly defined
       value overloading formerly defined values.

       Finally, any command-line-provided parameter takes precedence on any configuration file

           User configuration file. See lazygal.conf(5) for format.

           Album root configuration file. See lazygal.conf(5) for format.

           Web gallery configuration file. Only the webgal and template-vars sections are red in
           these files. The configuration applies to the gallery representing the directory of
           the configuration file, and all of its sub-directories, unless another configuration
           file in a sub-directory overloads some of the defined configuration values. See
           lazygal.conf(5) for format.


       The size string follows the same syntax as ImageMagick's.

           Height and width both scaled by specified percentage.

           Height and width individually scaled by specified percentages.

           Width given, height automatically selected to preserve aspect ratio.

           Height given, width automatically selected to preserve aspect ratio.

           Maximum values of height and width given, aspect ratio preserved.

           Minimum values of width and height given, aspect ratio preserved.

           Width and height emphatically given, original aspect ratio ignored.

           Change as per the supplied dimensions but only if an image dimension exceeds a
           specified dimension.

           Change dimensions only if both image dimensions exceed specified dimensions.

           Resize image to have specified area in pixels. Aspect ratio is preserved.


       Tag filtering supports regular expression matching thanks to the 're' module of Python.
       All the filter matchings can be indicated to lazygal by successive uses of the
       'filter-by-tag' option, or by giving a coma-separated list of keywords.

       We illustrate here how more elaorated tag filtering can be done.

       We want to export only the images that have the tags 'lazygal' AND 'hiking'.

                   $ lazygal --filter-by-tag=lazygal --filter-by-tag=hiking


                   $ lazygal --filter-by-tag=lazygal,hiking

       We want to export the images that have the tags 'lazygal' OR 'hiking'.

                   $ lazygal --filter-by-tag="(lazygal|hiking)"

       We want to export the images that have one of the tags 'hiking_2012', 'hiking_2013',
       'hiking_France', etc.

                   $ lazygal --filter-by-tag="hiking_.*"

       We want to export the images that have the tag 'lazygal', AND one of the tags
       'hiking_2012', 'hiking_2013', 'hiking_France', etc.

                   $ lazygal --filter-by-tag="lazygal,hiking_.*"
