This IV is using a href sources as "image" src while the IV idea is to show it instead of original article images.
It brings the cases when the hidden (non visible by ordinary article reader) a href sourcewill change the original article image.
It is not corresponding to the rule of the IV creation:
"Your IV page should show the entire text of the article, along with all the headings and subheadings, quotes, cover and other photos, videos, and other kinds of embedded content from the source page."

A href sources (even if if the corresponding cases of some "images"). are not the pictures viewed while the reading of the original article.
