Adjust image width on Collection page (for mobile)

[jangi]

Good Day. 

I'm currently using a third-party theme on Shopify. Support of this theme has been no help at all, and was wondering if someone can help me on this issue. Our collection page banner images are perfect on Desktop but on mobile, it cuts off in reference to the width of the image. Is there anyone that can assist in adjusting this in our code?

This is the layout of the mobile: as you can see it's cut off the two images on the edges.
