How to use thumbnail sorl to resize while maintaining aspect ratio?

Не выводит изображение. Устанавливал по документации.

{% load thumbnail %}

{% thumbnail new_item.photo "250x250" padding=True as im %}
          <img src="{{ im.url }}" height="{{ im.height }}" width="{{ im.width }}">
{% endthumbnail %}

Answer 1

{% thumbnail image "100x100" padding=True as im %}

Answer 2

At the specified height and width, the aspect ratio of the file will not be maintained. When padding, sorl will fit the image into these 250x250 leaving white margins (or another color if specified).
