Removing the borders will have no effect as they are not part of the picture, they just surround the picture. You have two options. The first, re-upload an image with more space at the top of the image … the crops Connections makes are center weighted. Another option is to try the Face Detect extension for Connections. It attempts to detect a face in the image and tells Connections to shift the crop center so heads are not cropped.
Hope that helps!
