wagtail-opengraph-image-generator

Wagtail Open Graph Image Generator will assist you in automatically creating Open Graph images for your pages.

There are a handful of configuration options to popuplate images with your page's content. Besides the title, there are options to provide a static company logo, subtitle, background image and page logo in the SVG format. While the resulting image will be a little bit opinionated, the defaults should work just fine in most cases.

The final image will be saved in the PNG format in a configurable Wagtail collection. It then can be used in your templates and code.

Features

Automatic creation of Open Graph protocol compatible images
Live preview and configuration in a seperate tab in the Edit and Create views
Several dynamic fields that can be configured to supply content for your generated image

Requirements

Python 3.7+
Wagtail 4
Django 3.0+
wagtail.contrib.settings in INSTALLED_APPS

Other versions might work but have not been tested.

Installation

Install with pip: pip install wagtail-opengraph-image-generator

Add wagtail_opengraph_image_generator to your INSTALLED_APPS

Finally, apply the migrations with python manage.py migrate

Usage

Once the addon is installed, you will notice a new tab in your edit/create view.

The injected new tab

This new panel will allow you to preview your new Open Graph image before you save it. Depending on your exact configuration this panel will provide slightly different options and customizations.

Embedding in your template

Accessing the generated image is done with an image tag. Make sure to load it in your template and call get_existing_og_image [page-object] to save the image in a variable. You can then use it as any other Wagtail image.

{% load wagtail_opengraph_image_generator_tags %}

{% get_existing_og_image self as og_image %}

{% if og_image %}
    {% image og_image original as og_image %}
    <meta property="og:image" content="{{ self.get_site.root_url }}{{ og_image.url }}">
{% endif %}

Examples

A basic example with a default background image, company logo and subtitle might look like this:
