I want each product category page to show that category's child categories
Each category would have it's own image
On each category page it should show a grid of all the child categories and their images
Each child category and it's image should link to that category page where all posts in that category will be shown
Preferably this would be done with a plugin so it's totally automatic, rather than having to add shortcodes to pages etc.
How do I do it?
