有没有办法可靠地检索最大版本的facebook专辑照片的尺寸？

import facebook

# Initialize the Facebook SDK
facebook.configure(api_key="YOUR_API_KEY",
                   secret_key="YOUR_SECRET_KEY",
                   app_id="YOUR_APP_ID")

# Get the user's ID
user_id = "YOUR_USER_ID"

# Get the user's album photos
response = facebook.get_object(user_id+"/albums")
albums = response["data"]

# Get the largest photo
largest_photo = None
for album in albums:
    photos = album["photos"]
    if len(photos) > 0:
        largest_photo = photos[0]

# Print the largest photo's URL
print(largest_photo["source"]["url"])
