Cover image

A Pelican plugin that adds a cover_image_url attribute to articles and pages. Includes settings for local and default images.

Installation

1. Download this plugin
2. Place it in your plugins directory
3. Add pelican-cover-image to PLUGINS in your settings file.

Or see the general Plugin installation instructions.

Usage

Add the attribute cover_image to your article or page metadata:

title: My super title
date: 2010-12-03 10:20
cover_image: https://images.unsplash.com/photo-1471644865643-fe726490270a # Can also be a local image file, see further

This is the content of my super blog post.

This will activate the cover_image_url attribute for all articles (including drafts) and pages (including hidden pages), which you can use in templates as follows:

Article template:

<img src="{{ article.cover_image_url }}" alt="Cover image">

Page template:

<img src="{{ page.cover_image_url }}" alt="Cover image">

Using local images

If you want to use local images in addition to full image URLs, you need to define in your settings file where those are stored:

COVER_IMAGES_PATH = "static/cover_images" # No trailing slash

Make sure that path is included in STATIC_PATHS so Pelican will copy all cover images to the output directory (see Pelican documentation):

STATIC_PATHS = ["static"] # Since /cover_images is a subdirectory of /static, it is included here

With the above settings, the cover_image_url for the following article will be http://example.com/static/cover_images/unicorn.jpg (format: SITEURL/COVER_IMAGES_PATH/cover_image):

title: My super title
date: 2010-12-03 10:20
cover_image: unicorn.jpg

Using a default image

By default cover_image_url will be empty if cover_image is not defined (either as URL or local file) in the article or page metadata. If you want to set a default image for all pages and articles, add one to your settings file:

COVER_IMAGE_DEFAULT = "https://images.unsplash.com/photo-1489513963600-afa31b458fec"

COVER_IMAGE_DEFAULT can also be a local image file, using the same settings as described above.

COVER_IMAGE_DEFAULT = "default_image.jpg" # Will look for image at COVER_IMAGES_PATH
