I use this snippet to save images to my imagefields on django models. This uses the very awesome requests library, so install it first
pip install requests
You probably want to have this be done on a celery queu, if the image is big enough.

def get_img_obj(url='',relativefile='',absolutefile=''):
''' Takes a url or a relative path to a file in the static dir and returns
an object suitable to be asigned in an imagefield = get_img_obj(url='url')'''
if url and relativefile:
raise UserWarning('Function save_image_in_field expects a URL or a Filename not both.')
if url:
r = requests.get(url)
data = r.content
if relativefile:
r = open(os.path.join(settings.STATICFILES_DIRS[0],relativefile),'rb')
data = r.read()
if absolutefile:
r = open(absolutefile,'rb')
data = r.read()
img_temp = NamedTemporaryFile(delete=True)
img_temp.write(data)
img_temp.flush()
return File(img_temp)
##### And you can use it like this:
## Asume that profile is some model and image is an imagefield of that model
profile.image.save('some name.jpg',get_img_obj('http://google.com/logo.jpg'))#url
profile.image.save('some name.jpg',get_img_obj(relativefile='images/logo.jpg'))# the file is on ~/django_project/static/image/logo.jpg
profile.image.save('some name.jpg',get_img_obj(absolutefile='~/userfile.jpg'))# you pass the full path to the file
