I want to resize my static files with sorl thumbnail but it doesnt work

here is my codes

```
{% if not new.photo %}

{% with path="{{STATIC_URL}}/images/empty-news.jpg" %}
{% thumbnail path "80x80" crop="center" as im %}
<a href="#" class="image"><img alt="" src="{{im.url}}" class="frame2"></a>
{% endthumbnail %}
{% endwith %}

{% else %}
{% thumbnail new.photo "80x80" crop="center" as im %}
<a href="{% url news_detail new.slug %}" class="image">
<img alt="" src="{{im.url}}" class="frame2"></a>
{% endthumbnail %}
{% endif %}

```

If I have image it shows image but when I dont have image I cant use default image because thumbnail doesn't work
