I have here hundreds of epubs of a special series. To get a cover-gallery I want to extract all the covers out of the epub. Using "export books" Calibre exports the epub and the Cover in 2 separated files. That's fine. But the covers (jpg) are all named with title and author, but not with the number of the issue of the series, though the name of the epubs are containing the issue number.

What I have to do to get the jpgs named correctly including the issue-number?

Again:
Name of the original epub: [series][issue no][author][title]
Name of the exported epub: [title][author] (that is not important, I don't keep these files)
Name of the exported jpg: [title] [author]
WANTED name of the exported jpg: [issue no] (title, author not necessary)

If it's not possible to do it with Calibre, any idea is welcome to get the covers extracted automatically.
