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.
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).
Run an extra optimization pass for each generated thumbnail.
Generate progressive JPEG images.
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.

is 'filename'). Add ':reverse' to reverse the sort order (e.g.

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

If a directory from the source album contains a file named
album_description, it is processed as a source of album metadata. See
