Shrinks image boxes on mobile... how do I make them bigger/square shape?

Hi there, this template shrinks the images under ‘Legal Services’ down quite a lot, how do I make them bigger again? Thanks for your help!

@rosespotdigital you can give them a larger min-height, in your project you set the min height to 0 on the boxes. I think around 250 - 300px will look fine.

Thanks very much, all fixed
