How to fill entire section with image when there's an empty space before a divider?

Hi! @tuanphan Hoping you can help me 🙂 

Do you know how I can remove the empty space above the divider, so that the image takes up the entire space? Hopefully that makes sense! See url attached.

Thank you

Hi,

I don't see divider. Can you take a screenshot of empty space?
