Bring the < and > navigation buttons in to the edge of the image and not put them at the width of the browser. Or provide a second option to use traditional over-the-bottom-of-the-image < > buttons, like the carousel hero uses.

Thank you for your suggestion @Admin !
I’m just adding two examples below to give our developers a visual on what you are looking for.
I see you mentioned two possible layouts for the lightbox/zoom navigation arrows. Is there one out of the two you have a preference for?
Thank you!
