How to get image size from url

Today I needed to get image size (width and height) from image urls. I am sharing my python code here.

import requests
from PIL import Image
from io import BytesIO


def get_image_size(url):
    data = requests.get(url).content
    im = Image.open(BytesIO(data))    
    return im.size


if __name__ == "__main__":
    url = "https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjcw6adFki0Rnm_aA1YNYXwLWCTzPKjLbG9hI0QweVAoLlNWzK2NQHez4RMhvh9A6WS1eSccU5Swsk2bewxXa9j0rYO3Gl7Jw8ht45n72SONTlwdALyDYJqWtcsW0IY6HFTmFjDuV1yvsRF/s1600/sbn_pic_2.jpg"
    width, height = get_image_size(url)
    print width, height

I used pillow - which is a PIL fork.

Feel free to comment if you have any suggestion to improve my code.
