When you double-click on the book that hasn't been opened before, first thing you see is the cover, and then you can scroll down to begin reading. This plugin does generate a physical jpeg file for the cover, but it doesn't insert it back into the book like the other methods do.

No method that changes the cover in calibre automatically inserts the cover into the book. It just doesn't happen. Here is an explanation I wrote a while back regarding ePub books and covers.

- Use the Content server to export the book from calibre.
- Use the modify ePub plugin to update the cover in the book.
- Convert the file from on format to another, ePub to ePub would work.
Covers will only get inserted into the ePub with the first 5 options above if there is an existing cover in the ePub that is properly structured and identified as a cover.
Currently if a cover doesn't already exist in the ePub or if the cover is not properly identified the only way to insert the cover is via a conversion, once more for the record a ePub - ePub conversion would work to embed the cover. |
