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


no body can help? we also want to fix it. remove it when you show subcategories will best.

thanks in advance.

I found it out you can set the tumpnails to 1x1 pixel so you cant see them anymore
