User blog:ThunderDragon2/Files that are used, but are marked as unused

A small list of files that are used on pages, but are marked as unused. Some files that are used are listed in Special:UnusedFiles, causing them to be deleted. It is seen that they are indeed used only after they are restored. Certain files are not updated even after restoration. Such files, when seen in the image lightbox, show that they are not posted on any page, even in Special:WhatLinksHere.

How to differentiate in an image lightbox (Left side = Used file marked as unused; Right side = Used file marked correctly):

Note: Files listed here might become marked as used, due to them being linked here. This is not a complete list; it's just an example.
