Changing image size for “Product Image” on Product Page

I am trying to customize my product page by creating a template through elementor. When I use the product image widget to display my products it shows the main product image and the product gallery is on the bottom of the main image.

I was wondering how would I:
1) make the main product image smaller
2) make the product gallery images smaller and if possible put the product gallery images on the left side instead of the bottom
