This gets me a small square FB thumbnail:
http://graph.facebook.com/5/picture?type=square
(UID example could be 5).
‘d like a larger image (75 or 100px?) that is still cropped at the same points as the thumbnail. I know the param square can be large, but then it loses its crop positioning. Is this possible?
Thanks in advance.
I was having a similar issue and went about solving it the hard way. This code will give you an imitation of a Facebook thumbnail in the largest possible size without losing resolution. Read more in the README.
