Where to change layout of product details?

Hi,
I cant find out where to change certain parameters of product detail pages.

Image 1 - when a user clicks on a category and then selects a vendor:
Where are the settings for the white background color?
Where can I switch off the showing of the product image?

Image 2 - when the user is coming from a product listing page to a product detail page: different look.
Where are the settings for this page?



I couldn´t find any relevant settings in DISPLAY / CONTENT MENUS.
I don´t think I need to make the changes in the PHP, do I?

Thx

Found the solution for image 1: The settings can be found in the "Hikashop Content Module" under HIKASHOP / DISPLAY / CONTENT MODULES.

For image 2, that´s still unclear to me...

Hi,

The settings are in Config > Display > Default options for product.
You can too customize the view via css or editing the view "product / show_default".
