Find Facebook user (url to profile page) by known email address

I have a list of email addresses from people that use my app. Is it possible to query for their facebook public data by email address?

Thanks Richard.

Any application can fetch users(application authorized users) facebookID in user basic information via graph api or fql. for exa. https://graph.facebook.com/me?access_token=[facebook returned access token]

it will return these information in JSON

{
   "id": "100001114785800",
   "name": "Stella Jackson",
   "first_name": "Stella",
   "last_name": "Jackson",
   "link": "http://www.facebook.com/profile.php?id=100001114785800",
   "birthday": "04/16/1987",
   "gender": "female",
   "interested_in": [
      "female"
   ],
   "timezone": 5.5,
   "locale": "en_US",
   "updated_time": "2010-10-08T13:26:10+0000"
}

Once you get user ID you can fetch user picture via graph api

https://graph.facebook.com/[user facebook id]?fields=id,name,picture https://graph.facebook.com/100001114785800?fields=id,name,picture

OR

https://graph.facebook.com/100001114785800/picture?type=small

type can be small, normal, large, square

Best luck Richard

Facebook use the facebook id to access user information via api or via FQL instead of email id.
