1. The problem
Some image links are full links to the original site image, when you download html from wayback.
Wayback page:
eg:
<img width="260" height="192" src="https://montagnesauvage.com/wp-content/uploads/2020/02/new-logo-2020.jpg" class="site-logo attachment-dyad-site-logo" alt="" data-size="dyad-site-logo" itemprop="logo" decoding="async" />
However, wayback processes these links to point to wayback archive image
