I'm using Magento 18.104.22.168 version and I want to add the option for the customers to upload their image on My account page.
I've added a new customer attribute of image file type in admin, and this works pretty fine. But it has only Maximum Image Width, Maximum Image Height options for the image. I would like to add two other inputs so I can specify the width and height for resizing the image when they upload their avatar.
Is there a way to do that? I'm also curios what module/class is used for the upload image attribute on customers.
