Option 1

Looks like this packagesatisfy your needs,

django-easy-pdf

Check the above package

Option 2

We can use templatetag filter

Let say you have image url in your html like below,

<!DOCTYPE html>
<html>
<head>
    <title>{{ title|default:"" }}</title>
        <style type="text/css">
            body {
                background: white url("https://www.some.com/some.jpg") ;
            }
        </style>
</head>
<body>
</body>
</html>

Now if we need to add this image into PDF then you can use that package library to handle it.

Create the file as myapp/templatetags/pdf_filters.py: 

from django import template
import urllib, cStringIO, base64

register = template.Library()

@register.filter
def get64(url):
    """
    Method returning base64 image data instead of URL
    """
    if url.startswith("http"):
        image = cStringIO.StringIO(urllib.urlopen(url).read())
        return 'data:image/jpg;base64,' + base64.b64encode(image.read())

    return url

Now we can load this filter

{% load pdf_filters %}
<img src="{{ ressource.image.url | get64 }}"/>
