How to display picture from memory in Django?

Question

I know how to show picture as a page from memory just using like this:

import cStringIO

mStream = cStringIO.StringIO(picBin)

return HttpResponse(mStream.getvalue(),"image/jpg")

But what if I don't want to show the picture as a page, instead I want to show it within a page, say using in HTML, does someone has an idea what I should set the "src" if the picture is loaded from memory?

You'll need to base-64 encode the image contents into a Data URI:

data_uri = 'data:image/jpg;base64,'
data_uri += mStream.getvalue().encode('base64').replace('\n', '')

Now you can shove data_uri into the src attribute of an image.

You can encode anything with a MIME type into a data-URI. It's pretty cool, but the problem is that browsers don't cache the data-URI images – Blender Sep 19 '12 at 02:52
In `python 3.4`, you need to write: `data_uri = b'data:image/jpg;base64,'` – 7stud Jun 24 '16 at 08:23
