Include category image

Hello everyone,

I use WooCommerce and I can not seem to include the category image at the top of my page under the header in the “category-product /” (the page that displays all products in a category). I would like to present my template so as to have the category image, the description and all products category as a result.
I searched a lot but could not find how to insert the image.

Thank you in advance for your help.
