How to display subcategories on each main category page ?

[Eljaouhari]

Hello everyone, I hope you're doing great !

I have an urgent task to accomplish by the end of the day !

I have managed using the backend-office to display each main category and it's subcategories when the products of a category are listed just like this picture..

The right side : the main cateogry and it's subcategories .

The left side, is where I want to display this module  + displaying the category and subctegory images.

How can I proceed knowing that I don't use a classic theme and I'm on PS 1.7 ?

Thanks in advance.
