Need Custom Code! Image click for custom quick view but not for product.

I am trying to create a custom code so when I click on an image, I get a custom "quick view" or lightbox to reveal more details and call of action. Similar to a quick view for a product but not product related. 

Thanks in advance. 

You can use a Lightbox Plugin (affiliate link) or use this link (non-affiliate link) to achieve this.

With plugin, you can create a Not Linked page > Add anything into this page > Then use plugin to make lightbox appear when click image. The lightbox content will pull content from not linked page
