Where there is a problem like that, I use the editor to set the cover using the desired image. I usually use the add cover tool, but setting the image as the cover is enough. Then, the metadata editor will get the right.

But, I'll have to add a warning. I just did this and there is a problem. It is something I had noticed before, but, hadn't connected the dots.

I needed an epub with multiple images in it, so converted a CBZ I had to epub. That duplicates the first image and adds it as cover.jpg.

Then, I edited the book and selected one of the other images and marked it as the cover. Saved and opened the metadata editor. Then selected the epub version and pressed the button to get the cover. And, as expected, it retrieved the image I had set as the cover. But, as I didn't want that to be the cover, I cancelled and opened the epub in the editor. As I have the options set to update the metadata and the cover when opening the editor, it did that. But, that means it replaced the random image I had marked as the cover with the one that the library had as a cover. Which is working as designed, but not what I really intended.

And, there is another problem if you use the add cover tool in the editor. That will change which image is the cover image, and removes the old cover image. Again, working as designed, but probably not quite what we expected. This I noticed a couple of weeks ago along with something that is definitely a bug. When this happens, other pages containing the either the previous cover image, or the new cover image, can get changed. That I have a fix for, and need to finish testing.

And doing all that, makes me realise there is no simple way to duplicate a file inside the editor. For a text file, it isn't to bad (new file, copy all and paste). For an image, it needs an export followed by an import. It works, but, in six months time I'm going to be wondering what all those images are that are lying around

I'd be happy if I could right click / copy image to clipboard in the editor like I can in the viewer. I'd be happier if in the metadata editor I could pick the epub format and click on cover icon (or right click maybe) and have it show me the current cover and the first 5-10 images...

You can copy image sin the editor by simply double cicking on them to view them and then clicking the copy button.

The editor allows you to view any image in the book and copy it to the clipboard using the copy to clipboard icon (see attached). You can also use the Add Cover tool (see attached) to select any image in the book and make it your cover. You might be able to get Kovid to patch this tool to the edit metadata editor book cover icon. Read this section to understand how to submit an enhancement request.

Additionally once you have an image copied to the clipboard you can simply paste it as the cover in the book details section of the calibre library. Just right click the big image of the selected book and select paste cover.

But, there is no way to paste that in as a new image. I can paste it over another existing image, but, I can't see a way to paste it as a new image in the epub.

I did try to add a new file with the appropriate file type. That gives a 0x0 sized image and show "Not a valid image" in the canvas. Pasting an image from the clipboard over that gives:

If the image is already in the book, why would you want to duplicate it? That is juts a waste of bytes.

My description above about the behaviour when you choose an existing image as a cover would be one reason. To be able to resize or otherwise fiddle with and reuse the image elsewhere is another. For that, it is probably better to export, make the changes elsewhere and import again. I don't remember exactly what I was doing at the time when I discovered this, but, I remember feeling that not being able to duplicate a file was missing function.

How large is your Calibre library?

My library can’t even be called a library when compared to those here. As of right now my main library has 720 books. That’s 20yrs of ebooks. The number will rise though because I’m going through and splitting omnibuses. I, also, have a knitting library, a box set/omnibus library, and a comics library. The boxset library is where I send the originals after I’ve split them.

My main or "Master" library currently has 1731 entries which consists of ebooks, paper books, and a single entry for each audio book. It also contains some fan fiction. I also have separate libraries for my paper and audio books. Creating a separate library for box-sets sounds like an interesting idea.

Size of Calibre library

I've been adding books to Calibre since early 2010.
At this time, I have 14,887 retail books. I will never get around to reading even a quarter of them. Right now, after almost ten years, I guess you could call it a "hobby".

Wow. I've been buying ebooks since 2002, and I only have 3875 bought books in my calibre library.

Perhaps you might have a minor ebook buying addiction, rather than a hobby?
