4 pictures instead on 1 on mobile view

Hello, 
Does anyone know how I can change the amount of product shown on mobile view?
Now all I get is 1 per page but I would love to have 4, so that the customers get an over view when they see my store.
The first picture is what it looks like now, and the second picture is how I want it to look like

Probably … I haven’t tried this … but go from website editing view to mobile view. Get your photos cropped or sized to your desired look, then fit it within the frame. I know on one of my sites I have one page where 2 photos are even on top of each other, so I think this is doable through advance editing. 
 

hope that helps. Please let me know. 

From what I can see I can only chose set sizes for the product images. When I go to mobile view, I can either ''manage items'' or ''edit section''. (If I go to 'edit section -> aspect ratio'). And that only changes the size of the images, not putting them next to each other.. 
Is there another way of changing / cropping the photos? 

THANK YOU!!!! ❤️❤️❤️
