Image Size in Starterkit-Master scaled up automatically

Hello Community,

in my local enviroment i’ve created a shop page with products. Now the product’s images are scaled up from 200px to 1040px. How can this happen? Is there a changeable configuration?
I used the shop.php template from kirby --> https://getkirby.com/docs/reference/panel/samples/shop

i hope you can help me!

Probably due to your styles?
