You can add or update a category image on both the Create category and Edit category screens.
Go to the Categories page and either click Create Category or use the Manage edit button on an existing category.
On the form, find the Image URL field.
Paste the web address of the image you want to use for this category.
Check that the URL points to a valid image that is publicly accessible.
Save the category.
Once saved, this image can be used wherever your storefront or theme displays category images (for example, on category tiles or navigation banners), helping customers visually recognise different sections.
