How to get all images from someone else's site folder?

Question

Parsing

Greetings
I liked the image at this address:
https://vk.com/images/icons/interesting.png
In the paths of the link, you can see that the desired image is in the icons folder. There are probably other images hidden in there. Question: How can I access them to see all the images in a folder?

Answer 1

The server responds to HTTP requests
when you send a request to get a specific file - it responds with this file,
when you send a request to view the contents of the directory - it sends you nafig,
because for security, smart people in the server settings close the view of the contents of the directory
Answer to the question:
0) Find out filenames by parsing html code
1) Go through filenames in the hope that there will be matches
2) Hack the server and change settings
