django-url2png 0.4

Install it with pip:

pip install django-url2png

Configure settings: API_KEY, SECRET_KEY

Optionally set optional defaults for the filter, especially THUMBNAIL_MAX_WIDTH

Use it in a template:

{% load url2png_tags %}
<img src="{{ url|url2png:400 }}" width="400" height="{% get_height 400 %}"/>

This uses the configured THUMBNAIL_MAX_WIDTH, which is set to 300:

{% load url2png_tags %}
<img src="{{ url|url2png }}" width="300" height="{% get_height %}"/>
