iOS - Facebook. Is an access token necessary or not for user pictures?
===

I am able to access a user picture in a web browser without providing an access token, using the url:
http://graph.facebook.com/ID/picture

I know it performs a redirection, but it works. 

However, when trying to access the same url in an iOS HttpRequest, I get an "invalid_token" response.

Is it possible to get a picture from an ID, in iOS without a token? If so, how do I achieve this? If not, how is it possible using the web browser?

Thanks!
