How to find all the same pictures on the site?

Question

Images

Good evening!
I was asked to find all the same pictures on the X site (alas, I can’t give a link) and send direct links to the found images.
Of course, there is no entrance to the administrative part and ftp.
It seems to me that there is a catch in such a task, and it seems that all knowledgeable people do it in three clicks. Tell me, is there any life hack for quickly searching for images on the site?
Now I'm stupidly downloading the entire site through Cyotek. The process is long.

Answer 1

Download wget with request logging . There are
a lot of options.
Starting from a self-written script in python, to picasa

Answer 2

I was asked to find all the same pictures on site X (alas, I can’t give a link)

already suspicious!
If this is a task - use a search by image in Google.
