Homepage main photo not responding to size changes

I have made my website using the Shapely theme. However when I resize the screen to mobile or tablet size, the main photo on the homepage isn’t sizing down to fit whatever device it is being viewed on. Does anyone know how to change this?
I have attached a screenshot of how it looks on a laptop screen and how it looks on a mobile size screen. You can see the image not changing size.

Thanks
