How to determine if a Facebook user uploaded a profile picture or its default value?

Is there a way to find out if the user uploaded the image to the profile or has the default Facebook user image via FQL or somthing else?

You can use the Python script below (as no programming language is mentioned) to make it work.

urllib.urlopen('https://graph.facebook.com/<PROFILE_ID>/picture?access_token=%s' % access_token).geturl()

This will provide you with the URL of your Facebook profile profile. If this URL contains <PROFILE_ID>, then it loads the image. In addition, the default Facebook image is uploaded.
