# simple using Django Rest Framework Serializer
# for image paths return something like this
images = ["/media/image.jpg", "/media/image01.jpg"]

for image in images:

    print reverse("proxy_image", args=[image])
    /images/image/media/image.jpg # this url download image from original url and returns it !
