Gallery of galleries

Hi All,

I’m a WordPress newbie and not really a coder, especially not a web coder, so please bear with me.

I am setting up a new site: https://www.allessex.photos and on the site I have used the Studio theme (https://www.mojomarketplace.com/item/studio-clean-and-minimal-portoflio-wordpress-theme).

I would like to create a gallery of galleries page. In other words, every gallery page I add with this page as it’s parent, should be represented by a single thumbnail. When the thumbnail is clicked it should open the corresponding gallery page. It could also be cool if it was possible to directly open the gallery into the theme default lightbox (I like that particular lightbox), but that’s an extra.

Anyone know of a plugin that will do that? Or maybe some easy code?

Oh, I should say that the fully manual HTML link way is a no-go for me.

Thanks

Rgds,
Peter
