What is the best approach to add a cover image *inside* an EPUB file using Calibre?
Or you could edit the metadata through Calibre on that book, place the image where it tells you and then do an epub-to-epub conversion and the cover will be inserted into the file.
Edit: This requires the epub to be freed from DRM.
