I'm using the REST API from Windows Live Connect. I can get all contacts from an user but I don't understand how to get their profile photo.
Here is the manual I'm using. http://msdn.microsoft.com/en-us/library/live/hh243648.aspx
I'm using the scope: wl.basic
and in a first time sent a request to https://apis.live.net/v5.0/me/contacts
.
