Simple question about recycle imageview

Hi all.
I tried a few things about recycling here in the forum but nothing very clear and explained.

what is the right way to use multiple images in a ImageView?

for example
i want to show a imageview where i will load around 50+ images with size 600x600 or more.

1 - the recycle its the correct function on this case?

What should I do to load all those images without memory crash or any other type of crash?

as I think it is
- Open app
- Show image on imageview
- Use recycle to...
