Best practice for infinite scroll gallery (handling thousands of images) in Vue js

I am building a page in my Vue js app that is going to display A LOT of images in an infinite scroll format.

I am planning to use a lazy load images library when scrolling down, together with fetching 50 images at a time.

My question is whether there are any other best practices I might miss for handling this use case?

Let's assume the user scrolls to the bottom and gets to 1000 images, do the images at the top (that are not visible) are removed from memory by the browser? is there any way to control it?
