Question

I want a view to return image data. so something along the lines of

return HttpResponse(image_data, mimetype=”image/png”)

I know I can do a file.read() to get the image data, but because the image is small (like 1×1 px) I want to just store it as a string object (or whatever object I can copy and paste in my code). This way, I save myself the disk lookup everytime the view is hit.

How do i go about this? I’m sure this is easy, I’m just not sure what terms to use for search.

p.s. I know that one does not normally serve images this way with Django.

Here is a simple example from the django-openid project

def logo(request):
    return HttpResponse(
        OPENID_LOGO_BASE_64.decode('base64'), content_type='image/gif'
    )
    # Logo from http://openid.net/login-bg.gif
    # Embedded here for convenience; you should serve this as a static file
    OPENID_LOGO_BASE_64 = """
