pelican-image-optimizer

This pelican plugin uses ImageMagick, PNGQuant & Gifsicle to optimize images for web. Using these tools give a fast and efficient result.

Requirements

ImageMagick, Gifsicle & pngquant are required.

On Ubuntu:

sudo apt-get install gifsicle imagemagick pngquant

On Fedora:

sudo yum install -y gifsicle ImageMagick pngquant

Installation

See the pelican documentation.

Usage

All the GIF, PNG & JPEG images of your blog will be optimized during the build. Adding IMAGE_OPTIMIZATION_ONCE_AND_FOR_ALL = True to you pelicanconf.py will optimize the images in the content folder directly. The files will be renamed _optimized, but once in the output folder, they will be renamed without the _optimized. The markdown files need to use the name without _optimized.

Example:

1. I write the article test with an image content/img/test.png linked in the template and saved in my content folder.
2. On pelican generation, the file is optimized in my content folder and renamed test_optimized.png. In my output folder, the file is test.png, so my markdown link still works.
3. On the next pelican generation, the file won't be optimized, reducing the time for the generation.
