How to change the Mobile Image on a Promotion Grid Impulse Theme ?

[MontseV]

Hello, 

I have an image on the promotion grid that displays well for desktop but when I switch to Mobile it cuts off part of the image. Would there be some way to change the image dimensions for the mobile display?

I don't really know much about coding and i'm not even sure you can do that. 

The theme isn't live but i can share the preview link? Not sure how else to share it.

Hope some one can help. 

Thank you

There is an option to add separate image for Mobile devices in Impulse theme.

With a promotion grid it only has one option doesn't give me the option to upload an image for mobile.

I did sort of, I had to redo the image and make it so it shows up okay for both. @Mik3StorM
