Hi Divingduck,
... just saw that you send another post on Tuesday, while I was preparing mine. Sorry for the confusion caused (if any)
As it appears, your change fixed the picture-gallery-issue ... well at least almost

. Within the galleries, there is some "extra content" - mostly "internal adds". - Have a look here:
https://www.wiwo.de/politik/deutschl.../26760374.html. - As a result only the first 5 pics go into the ebook, and the additional text is only for 7 out of 17 in ... I suspect these are tweaks to nag readers to buy premium ...
Due to the changes in the Articles (The Teaser-Text no longer seems to start with a location), this additional code of mine (no longer included in your version) for the css seems deprecated:
Code:
.hcf-location-mark {font-style: italic; font-weight:bold}
.c-overline {font-size: 1em; text-align: left;font-style: normal; font-weight:bold}
However, I'm a bit surprised, that the .c-overline format does not catch any more (also tried other stuff, like italics and smaller fonts), as the insertion of the colon afterwards in your code still works ...
I won't play with this any longer for now ... well let's say for this year

.
Thanks and all the best to you
Hegi.
