XF 2.1 How to edit lightbox template

[dethfire]

I want to add a noindex tag in the lightbox template, but I can't find one. lightbox_macros doesn't seem to be it. When viewing an image in lightbox I can inspect and there is a framework, but it isn't contained in any template.

For example, where does this template live?

If I inspect in chrome I see a framework, but none of it exists in the lightbox js files. How is this page generated?
