Batch Crop & Straighten Fashion e-commerce images.

Hello to all, 

I've been trying to figure out a way to batch crop and straighten fashion e-commerce images, be it in a script or action to simplify the job. 

I would like to center the model in the image and be able to give the same pixel padding to the bottom and head. 

This generally takes up most of the time to do and I'm sure there must be a way to do this faster and more conveniently. 

Thanks in advance and attached are some sample images.
