I have installed a Jekyll based website which has a config file _config.yml. The file contains following section where avatar image is path is specified.
author:
name : "name of the author"
avatar : "/assets/images/avatar_logo.jpg"
I want to adjust the size of the avatar image on the final rendered web's home page. Most of the search I did was related to the markup pages but this is a the main config file which is in yml.
Not sure how to change/adjust the image size here.
