Pesky server error on Python web app - django

Question

I've been having a problem with a website that I'm working on not attaching pictures to html emails. Thought I had it fixed but then every time someone tries to register on it I get a Server Error (500). I've only changed a couple of references so no idea what went wrong there, anyways error log is as follows:
2016-08-31 08:26:15,757 :Internal Server Error: /register/
Traceback (most recent call last):
File "/home/asranet/.virtualenvs/testenv/local/lib/python2.7/site-packages/django/core/handlers/base.py", line 149, in get_response

fp = open(os.path.join(os.path.dirname(__file__), f), 'rb')
IOError: [Errno 2] No such file or directory: u'./adWind/static/Images/asranetLogo.jpg'
I checked and the file is there. No idea how to proceed, could really use some help. Thank you in advance!
P.S. here's the code for email functionality:

msg.attach(msg_img)

In Django the static directory is usually under a module_name directory. I suggest changing your paths into a relative one:
msg.attach_file('static/[module_name]/Images/asranetLogo.jpg')
and
f = 'static/[module_name]/Images/asranetLogo.jpg'
