How to level the delay of non-instantaneous image compression?

Question

PHP

I compress images using a PHP solution https://github.com/psliwa/image-optimizer _ _ _ _ in order for it to be displayed, you need to refresh the page (this is if hard caching is not enabled on the nginx side, otherwise it’s a disaster :). How to organize a chain so that the image is guaranteed to come to us?
