Hi
Forgive me if my report is a little fuzzy.
Since it was implemented in late 2019, I use nearly always the inline display for notes with ePub3 books and set this as a permanent option.
However, I just observed today what could be a not-so-good side-effect of this option.
I have an ePub3 with some hundreds of inline notes nicely displayed. Very fine.
This book has also about ten images, listed in a page. I linked each entry of the list with the corresponding image further in the book.
When I read the book with Koreader, I realize that it displays the image link as a pop-up endnote (with text) but does not display the image.
So it seems that I have to choose between
1. - a classical display of endnotes / good display of images from the list
2. - a nice display of inline notes / faulty display of images from the list
Here is the code I am using:
for inline notes
<a class="noteanchor" epub:type="noteref" href="chapitre20.xhtml#ftn1" id="bodyftn1">[1]</a>
<aside class="ntb" epub:type="footnote" id="ftn1">
<p class="note"><a class="notesymbol" href="chapitre9.xhtml#bodyftn1">1</a> text of the inline note.</p>
</aside>
for plain images in the list
<p class="Biblio"><a href="chapitre9.xhtml#Image1graphic">1. Title of the image</a></p>
<div style="text-align:center">
<img alt="Image1" id="Image1graphic" class="frameGraphics" src="images/image003.png" style="width: 97.0%; height: auto;"/>
</div>
<p class="Caption">Map 1. Legend</p>
Calibre displays properly the link to the image and its viewer displays the notes as pop-ups.
