Make titles and captions appear under a gallery block, NOT on top of the lightbox images

Site URL: https://georginasleap.squarespace.com/

Hi. I'm trying to change the formatting of the titles and captions in the gallery blocks of the project pages of my artist's portfolio site. It's a 7.1 site. 

you can have a look using the password : susan123

Please look at the demo page on the index of thumbnails. The bottom row, on the left, called Gallery Template Page. With a url

/work/gallery-template-page.  It's just a practise page.

1. I want BOTH the title and captions to appear under the images as you scroll down the project page. I don't want any text at all to appear on the lightbox- ed images. Is that possible? 

2. I'd also like the captions to sit a bit further away from the image than they do now - ideally so they are equidistant between two images. This is because sometimes I want to use them as short statements that tell the developing narrative of the page, rather than referring directly to the image above them.

Any help hugely appreciated, THANK YOU. 

Do you still need help?
