How to display Product Category picture on widget?

Hi, how to display the picture of the product category?
I would like to show the picture instead of text.
Help is appreciated.

Hey there,

I hope you are well today and thank you for your question.

However, I’m not entirely clear on your request.
Just to be clear, you want images to represent each category in the sidebar?
(see image attached)

Best regards,

Thanks for replying!
The suggestion works for me too.

But what I really want is a list of pictures showing the list of product category, instead of showing it just in text form.

category.PNG is what I desired.
category2.PNG is a widget from product category. It just showed texts, but I want it to shows picture and text.
