How do you remove this large blank space from images?

This happens when I upload an image onto my site. There is a really big gap at the bottom. How can I fix this?

Ohh, I see. Thanks a lot!

You have this code in Custom CSS box

Also, is there a way to drag these images to make them smaller?

You can add a Spacer Block on left and right of image to make image smaller
