Hi, I have the Propulsion Theme and I when adjust the image sizes under Products>Feature Media section it doesn't work on the front end? I would like to make the main product image much bigger on the product page then the default 450x355. When I change the width and height in the WooCommerce>Settings>Single Product Image it doesn't change the image size on the front end? After make the change in the backend I have tried using both the 'Regenerate Thumbnails' plugin and uploading a new product and new image and it still doesn't work.
How can I make the main image on the Product page much bigger (say 800x1000) or even custom to the product size that I am adding?
