Some time ago in the site structure section, a path and its child attachments for graphic files appeared.
Path example: /content/example/100x100/image.jpg

When looking through the section - Pages in search and making a selection of excluded pages, all paths to graphic files now have the status: Poor quality.
And their number is constantly growing.
How to fix this situation and find the reason for hitting paths with graph files as pages?

Answer 1

The problem was found in the incorrect operation of the routing.
