Retrieving Facebook's user avatar - how to define dimensions -
i noticed facebook's user avatar has 160x160px default. is there way can have same picture in larger size (180x180 example)? what's best approach if want re-size 90x90? try this (graph api example: 12345/?fields=picture.height(90).width(90)). you can define "type" (small, normal, large, square).
