How to make sure that images are loaded in F12-Network Chrome?

Question

css

I want to check the image for preload. For the eyes, the loading of images is not noticeable, so it is difficult to understand the picture loaded on the go or was already loaded before opening it. Heard it is possible to be convinced in F12-Network - the picture is loaded before addition in DOM. But I looked all over there and didn't understand where it was written.

What do not you understand? Here is a screenshot: there was a request to the server, the server answered 200 OK, gave the image to the browser... What is the question?
