Non-replacable covers

fvdham · 07-19-2012, 03:03 PM

I'am stuck with the following:
I have around 8000 e-books in the library. Around 50% of them have non-replaceable covers.
Is there a easy way of changing them to "replaceable" as I want to update many covers with better one's.
I searced the forum but could not find a solution.
The insert or replace option of the Modify epub plugin does not do the trick. I get "double covers" in the ebook.

Could anybody help me out?

Modify ePub is the best option you have. If you get double covers, it is because whoever defined those ePubs did a really crappy job, and no automated tool out there is going to be able to detect that what exists in there is intended as a cover rather than "some page" in the ebook.

Use Modify ePub to get a correct cover inserted, then open in Sigil to strip out any inside covers you don't want.

Thank you for the quick response.
I've never used Sigil; I'll give it a try.

If you haven't used Sigil before there are a couple of things you should know...

(1) the Open With plugin is darned handy to use to be able to launch Sigil directly from calibre (particularly with a keyboard shortcut).

(2) the currently released Sigil 0.5.3 is horribly crash-prone (on Windows at least) particularly for the actions you want to do. For instance do *not* do this sequence:
1. Open ePub
2. Double click on the html cover page you think you will be removing
3. Switch to code view (such as to see the image name)
4. Right-click on that html page in the book explorer and choose "Remove".

I would suggest using an older more stable version (such as 0.4.2), or else do any remove operations before you do any actions that involve switching to code view (like as mentioned above or opening a stylesheet).

You should of course also remove the associated cover image for an inner cover or else it will be orphaned. You can either do that in Sigil, or just delete the html page and then run Modify ePub with "Remove unused image files" afterwards.

Thanks, I had already problems with the version I'm using.
