Selectively removing padding between Project gallery media in 7.0

Site URL: https://john-coleman-voum.squarespace.com/landing-pages-emerson

It's been years since I've updated my portfolio so I'm a bit rusty—and I'm unfortunately I'm still running on 7.0 and can't afford to rebuild under 7.1 right now.

Anyhow, I need to remove the padding between some images within a Project gallery. The site I'm linking to is just an example. I need to reduce the vertical padding between the second and third images to 0px, but keep the padding between the first and second images as is. And I'll need to repeat this process for several other images that I will later upload.

Any help is appreciated. Thank you.

Which part are you mentioning? Can you show up some screenshots?
