Hi,
The HikaShop content module, like any Joomla module, displays in a specific position of your template.
Like any Joomla module, you have a setting to display the title of the module at the top of the listing.
When a module displays a listing of products, there is no mechanism to have it display the name of the category and its image at the top of the products listing.
When a module display a listing of categories, when you click on a category, the products listing is actually displayed by a menu item that you selected in the "menu" setting of the module. So similarly to what I wrote in my previous email, you can edit that menu item settings to make it display the category name and image at the top of the products listing.
