The issue appears immediately after importing the book from my Kindle into Calibre. On my Kindle, a freshly downloaded-from-Amazon copy of the book looks fine. When I import it into Calibre by hooking my Kindle up with Calibre open, going to the Device from the top bar, right-clicking on the book and saying Add Books to Library, then View the file, the images are gone (except for the cover) and replaced with boxes with question marks in them (see below). The only plugins I've got installed are DeDRM to do its unmentionable thing and Hyphenate This. One DeDRM would have been active on the book by this point.
Here are a few screenshots of what the freshly added book looks like:
The question mark here is supposed to be a sort of Penguin Random House logo:
[Images violate Posting Guidelines for size - MODERATOR]
The one here is supposed to be a map:
[Images violate Posting Guidelines for size - MODERATOR]
The one here is supposed to be some kind of squiggly icon at the top of the page:
[Images violate Posting Guidelines for size - MODERATOR]
And, if I understand what you want, this is what shows up when I select one of the "images" in the Viewer and tell it to Inspect:
Code:
<img class="w100" alt="" src="../images/00007.unknown" calibre_f3fa75ca98eb4413a4ee413f20f60226="0" style="-webkit-column-break-inside: avoid;">
I assume since the word "unknown" is in there, something is not coming across when the book is imported.
