[Answer]-Django don't serve static

Once you make sure the paths are correct, you are going to want to use the proper format in your templates, the last format recommended by the Django team is:

{% load staticfiles %}
<img src="{% static "my_app/myexample.jpg" %}" alt="My image"/>
<link href="{% static "themes/css/bootstrappage.css" rel="stylesheet"/>
