item page per image

I’m using the Hitchcock template at https://www.netvalu.net/photography/

In a post of gallery type, by default if I click on any image inserted to this post (via Add Media), the browser will show me a full size of that image.

What I’d like instead is a page with some more information on the image.

Is this something I will need to create by myself for each one of my images in the portfolio, or does Hitchcock comes with a template page for that purpose?

Thanks,
Yuval
