Thanks. I'm still rethinking that. It was a quick solution to show the images especially the otherImages(which are predominantly other map images) full screen. There's value in seeing the details up close. But I might try a different design, maybe a carousel in the future.
btw, why do you think it's invasive? in what sense?
Making the browser window fullscreen, while the user is not clicking on a fullscreen button.
I see. So adding a fullscreen button instead of the cursor: zoom makes it non-invasive?
