Unload when out of the viewport

[ndtreviv]

Is your feature request related to a problem? Please describe.
I have a page with potentially 1,000 images on it. I'm worried about memory load on the browser as the user scrolls down the page. Lazily loading in will help to start with, but only if the images get unloaded when they scroll out of the viewport again.

Describe the solution you'd like
I'd like to be able to configure a LazyLoadImage to be unloaded when out of the viewport.

Describe alternatives you've considered
Pagination.

Additional context

Bump. I'm currently using react-intersection-observer to do unmounting.

I see this is an old issue, but it would be a useful addition if it's still under consideration. *Edit, I was also able to implement react-intersection-observer for my needs
