Hello Brett,

Thank you for getting in touch with us.

Please note that LayerSlider is a slider plugin, so generally it was not meant for this kind of gallery usage. But you can still achieve something similar, altough it might need more work than a dedicated gallery plugin would.

For example you could add your images as separate layers and then apply a scale value on them on hover. So they get enlarged on mouse over. 
You could also add each image as a new slide and enable fullscreen mode on the slider, so it enters fullscreen when double clicked.
Alternatively, you could create a second slider which would be popup layout. And it would be triggered when an image is clicked in the original slider, and it would contain all of the images in a popup window.
