An HttpResponse is a 'file-like object', which means you can
call .write() on it just as if it was a real file. I would have one
view creating the image, and one view producing the HTML page which
refers to the image in an img tag via the image view's URL.
for example:
in the urlconf:
url(r'my_image/(?P<my_param>\w+?)/', 'myview.image',
name='image_view'),
url(r'my_view/(?P<my_param>\w+?)/', 'myview.view', name='html_view'),
and in the template:
<img src='{% url image_view my_param %}' alt='whatever'>
