If your form is Model Form .then jus try the below code.

from django.core.files import File
from django.core.files.temp import NamedTemporaryFile

class InputImageForm(forms.Form):
    image = forms.ImageField()
    class Meta:
       model = YourModel



def get_image(request):
    if request.method == 'POST':
        form = InputImageForm(request.POST, request.FILES)
        if form.is_valid():
            image = request.FILES['image']
            save_image_from_url(form,image)

        else:
           form = InputImageForm()
    else:
        raise Http404



def save_image_from_url(model, img):
    r = request.FILES['image']

    img_temp = NamedTemporaryFile(delete=True)
    img_temp.write(r.content)
    img_temp.flush()

    i = model.image.save("image.jpg", File(img_temp), save=True)
    return HttpResponse(i.read(), mimetype="YOUR MIME TYPE")
