Automatic photo album generation and thumbnailing for Pelican.

Project description


Pelican-Albums is a plugin for Pelican that helps you to easily manage your photo albums (or galleries).


  • Easily reference an image in your album path using {image}album/image.jpg.

  • Automatically create a thumbnail for an image in your album path using {thumbnail}album/image.jpg or {thumbnail:NxN@Q}album/image.jpg.

  • Automatically create album pages by adding a page to an album directory.


To install pelican-albums to your pelican installation use:

$ pip install pelican-albums

Then, add ‘pelican_albums’ to the plugin list in your

PLUGINS = ['pelican_albums']


Pelican-albums provides a couple of settings:

  • ALBUM_PATH (images): What directory inside content contains your albums.

  • THUMBNAIL_OUTPUT_PATH (images/thumbnails): What directory inside the output directory will be used to store thumbnails.

  • THUMBNAIL_OUTPUT_FORMAT (JPEG): As what format the thumbnails should be created (JPEG or PNG).

  • THUMBNAIL_DEFAULT_SIZE (192x192): What the default size of a thumbnail should be.

  • THUMBNAIL_DEFAULT_QUALITY (80): What the default quality of a JPEG thumbnail should be.

  • ALBUM_SAVE_AS (albums/{slug}.html): Where to store album indexes.

  • ALBUM_URL (albums/{slug}.html): The URL scheme to reference an album.


To create a new album, just create a new directory in the ALBUM_PATH (the default is content/images) and place the images inside it. Please note that pelican-albums does not offer facilities to rotate or resize the images for you (except for creating thumbnails) at this moment.


Pelican-albums will automatically generate the requested thumbnails at the requested sizes. It will check the mtime of the original file to that of the thumbnail to check if the thumbnail should be refreshed.

You can specify the size and quality of a thumbnail on different places:

  • Inside the {thumbnail} tag: {thumbnail:128x128@80}album/image.jpg

  • In the metadata of the content: Thumbnail-Size: 128x128@80

  • As a parameter to the album.thumbnail(spec=None) in your templates.

  • In the global pelican settings.

A thumbnail size specifier can have a number of different forms:

  • WIDTHxHEIGHT – Crop and resize an image until a thumbnail of these exact dimensions is the result (f.e. 192x192).

  • DIMENSION – Shorthand for DIMENSIONxDIMENSION (f.e. 192).

  • WIDTHx – Create a thumbnail with the given width but keep the original aspect ratio so the height might vary (f.e. 192x).

  • xHEIGHT – Create a thumbnail with the given height but keep the original aspect ratio so the width might vary (f.e. x192).

You can optionally add an @nn suffix to the size to indicate the thumbnail quality that should be used (f.e. 192@80 for a 192x192 thumbnail at 80% quality). This specifies the JPEG file quality and does not apply to PNG thumbnails.

Album pages

By creating a page inside an album folder, a page will be generated using the album.html template. Both the album and the page will be available inside the template. The page object works exactly as the regular pelican page objects.

The album object has several properties:

  • images – The images contained in this album.

  • albums – A list of sub-albums (if any).

  • pages – The album pages for this album (you can create multiple pages for each album if you want).

The image objects returned by album.images have the following properties:

  • album – The album this image belongs to.

  • filename – The filename of this image.

  • url – The URL of this image relative to the site URL.

  • thumbnail(spec=None) – A method that returns the URL of a thumbnail of the given (or default) size and quality relative to the site URL.


An example template for album pages (save this as album.html inside your templates directory):

{% extends "base.html" %}
{% block title %}{{ page.title }}{%endblock%}
{% block content %}
<article class="page">
        <div class="title">
            {{ page.title }}

    <div class="entry-content">
        {{ page.content }}

    <div class="album">
        {% for image in album.images %}
            <a href="{{ SITEURL }}/{{ image.url }}">
                <img src="{{ SITEURL }}/{{ image.thumbnail(page.metadata.get('thumbnail-size')) }}"
                     title="{{ image.filename }}" />
        {% endfor %}
{% endblock %}
