Broken Image LInks to cdn.qnez.net

Started writing this on Embracing Justice | BigCloset TopShelf, then realised it was almost certainly an issue for Site Admins, and may also affect other stories images as well, so below is mostly a direct Cut & Paste of what I intended to post, on that stories latest chapter

Almost the entire series is missing the Marshall Badge Picture, only the file name shows up.
The Image is hosted on a site that at first glance, appears to be external to BCTS, that has gone down, as direct linking gives this error with both Pale Moon (A Firefox Based Browser), and Chromium (A Chrome based Browser).
Can't find the server at cdn.qnez.net
The rest of the cdn.qnez.net web address, looks like it's also a BCTS link, but maybe to an old site address, or a backup, no longer used?
http://cdn.qnez.net/topshelf/system/files/u9968/142px-US_Mar...
This appears like this (Note if site returns pic will appear below)

Strangely, the posts from Educational Justice: Chapter 15 to Interpol Heartburn: Chapter 17, use the direct BCTS Address

This shows just fine, being a direct BCTS link

Why it switched back to using the now broken link for later Chapters, only the author/site admin might know, but SNAFU is a good guess.
Switching the image links host site (cdn.qnez.net) to the main BCTS address (bigclosetr.us) will fix the issue.
Easy to do in Notepad++, using Find and Replace, on the html version I downloaded.
I doubt that will work for the entire site, but site admin should have tools to change all image links on the site, with a similar search/replace function.
