Hello, All. I'm a relative amateur when it comes to the entirety of WordPress so I need some advice on where to start on a gallery I'm trying to build. Simply put, I am trying to build a page (on a Responsive child theme, 1.7.2) in which all my galleries initially are viewed as a grid of single image thumbnails. Clicking any thumbnail then creates a clickable slideshow of that gallery (with caption underneath at the top of that page, while still preserving the grid of single image thumbnails below it.
I've experimented with WordPress galleries, NextGen Gallery, and a number of other gallery plug-ins, but have found nothing close to what I desire to do here. I'm at a loss and not sure if what I want is just impossible or if I'm just looking in the wrong places.
Any help would be appreciated.
