Hi folks,

I've got a number of epubs added to Calibre from various sources (Kobo, Overdrive, darknet) that Calibre doesn't find the cover for. These almost always have a cover (usually called "cover.jpg"!).

I would have guessed the problem was in content.opf but here are two examples that are reasonably similar. On a book with no cover, the relevant parts of content.opf that mention "cover" are:

  <metadata ...
    ...
    <meta content="cover.jpg" name="cover" />
    ...
  <manifest>
    ...
    <item href="Images/cover.jpg" id="cover.jpg" media-type="image/jpeg" />

and an epub with a cover is quite similar:

  <metadata 
    ...
    <meta content="cover" name="cover" />
    ...
  <manifest>
    <item href="Images/cover.jpeg" id="cover" media-type="image/jpeg" />

I've left out references to cover.html or cover.xml.

I also have some epubs that don't have the meta content part, and only seem to have a cover.html (and related jpeg).

Any suggestions why Calibre isn't finding covers? A search of mobileread didn't turn up anything useful.

For a bonus, is there an easy way go assign "cover.jpg" or "cover.jpeg" from an existing epub as the cover. I've got a number of books I want to do this for, and manually exploding the epub to extract the cover is a bit tedious.

Cheers,
Simon.
