Getting a facebook profile picture from an email address

Question

I\'m trying to get a user\'s facebook profile picture based on their email address. Effectively, I want to offer my users the option between using Gravatar for their image,

Answer 1

I see this question has a couple of years already but the same search approach can be taken using the Graph API:

GET https://graph.facebook.com/search?q={EMAIL}&type=user

You can try this on the Graph API Explorer. You don't get the profile picture directly but you get the user id which you can easily use to get the public profile picture.

https://graph.facebook.com/{UID}/picture
