Woocommerce catergory photo is HUGE

Hi, I’ve just started adding in my products, and wanted to use a product image per category- which I’ve done through woocommerce. This is fine for the main category page, but when I click on that the category image to go through to that catergory, the image is MASSIVE!! And I can’t find any where to change it! I’ve tried through woo, through my wordpress settings etc, and nothing is changing! It looks fine on the mobile, but on the computer, it’s terrible!! As it’s so massive, it’s blurry and horrible!

Please can I get some help?! Ocean WP theme.

Thank you! xx
