how to remove thumbnails from detaild page

Good afternoon,



I have subcategories on my website with 2 rows of images. I want to hold them.

But when you click on a categorie with the image. You will get the subcategories but also in the left corner the main image from the catergorie.



Does someone know how to hold the images on the categories but delete them from the subcategories?



Please watch my picture to understand





Thanks in advance
