Images not showing in the product categories.

Sir,

I have two problems in my website.

First:

I have added the product categories in my home page but the images are not showing in the categories. I have checked all the settings but they are not showing. Please fix the issue for me to show the images.

Second Issue:

The second issue with my website is that I have added the brands tabs in my website but the brands logos are not showing in this field. I am making my website same as your demo website. Please also solve this problem so the brand logos should show.

I have attached the screenshot. So, you can understand my website problem thanks.
