How to download all pictures from the site (landing page) in the browser, or the entire site?

Question

HTML

Hi all. Faced with the problem of downloading a one-page site. I download the site completely from the browser, however, the pictures that are written in the background in css are not downloaded. I tried to search in the inspector somehow here , all in vain.
Maybe someone also faced such a problem? Do not offer programs for windows, manually downloading large volumes is "time-consuming".
