My iOS app fetches the profile picture for each person after they login via Facebook, using the URL graph.facebook.com/<user id>/picture?type=large. However, the picture coming back is often much smaller than the actual profile picture is when you see it on Facebook, sometimes around 100x150. How can I fix this?
You can specify a width= or height= parameter instead of type if you want more control over the size you get back. I can't find it currently documented but in my code I noted that type=large means about 200px wide.
