Is it possible to get the original image from the img tag?

Question

HTML

there is such a problem, it turns out there is html in it with an img tag with src = https://c.mail.ru/c/6?kxbe3qmj.chb
well, not necessarily like this, but for example,
I tried to get a picture simply by sending a request to this url, but the problem is the fact that this url always gives a random image,
I'm sure that there is some way to get exactly the image that is already displayed on the site using js,
tell me plz
