Captions for Wagtail Images

A Django app for extending the Wagtail Image model to add captions and alt fields as well as the extraction of IPTC image meta data.

Installing

Install using pip:

pip install wagtailimagecaptions

Settings

In your settings file, add wagtailimagecaptions to INSTALLED_APPS:

INSTALLED_APPS = [
    # ...
    "wagtailimagecaptions",
    # ...
]

You will also need to set a custom Image model in your setting files:

# settings.py
WAGTAILIMAGES_IMAGE_MODEL = "wagtailimagecaptions.CaptionedImage"

Migrating

Heads up! If you have existing images, you will need to create a data migration operation to move the old images into the new model.

How to Use

The custom Image model, CaptionedImage, adds four new fields to the Wagtail Image model: alt, caption, credit, iptc_data. When a new image is uploaded via Wagtail's media library, the app will attempt to extract any IPTC meta data found in the file and fill the alt, caption and credit fields. All IPTC meta data extracted is also stored in iptc_data.

Example use in a template:

{% load wagtailcore_tags %}

<img src="{{ image.url }}" alt="{{ image.alt }}">{{ image.caption|richtext }}

Adding date paths to image uploads.

To add date paths to the image upload path, you can set WAGTIALIMAGECAPTIONS_UPLOAD_TO_DATE_PATH in your Django settings file with a valid date format.

# settings.py
WAGTIALIMAGECAPTIONS_UPLOAD_TO_DATE_PATH = "%Y/%m"
