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 launching:
$ lazygal -o /var/www/MyAlbum /home/user/SourceDir
lazygal will analyze the contents of the source hierarchy and will
(re)create the target hierarchy, but with all the bells and whistles
defined by the templates. Only missing parts or parts that are not up
to date will be generated.
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.
Show program's version number and exit.
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 directory).
-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.
Clean destination directory of files that should not be there
(default is to print a warning but not to delete).
Exhaustively go through all directories regardless of source
-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).
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).
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 unlimited).
Sort order for images in a subgallery, among 'mtime', 'filename',
or 'exif'. (default is 'exif' which is by EXIF date if EXIF data is
available, filename otherwise, sorting EXIF-less images before).
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' or 'dirname' (default is
'dirname'). Add ':reverse' to reverse the sort order (e.g.
Level below witch the directory tree is flattened. Default is 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
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
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,
A theme maps to a directory that contains the following items:

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.
Each file which name starts with SHARED_ is copied to the web album
destination under the directory shared and is aimed at being a shared
resource accross your web album (CSS stylesheet, button, etc.).
Each file which extension starts with t is processed through the Genshi
text template engine before being copied. See
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 4. 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 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
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 lazygal/defaults.conf.
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 value.
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.
