any way to store multiple covers

[cybmole]

or at least the previous one ( like with the original_Xxxx book options ) ?

I have been experimenting with resize cover plug in, but there is no obvious way back to what the cover used to be if you forget the previous dimensions/can no longer find an online version for download

does the database rely on seeing a file name of cover.jpg in the book folder, if so could I simply keep copy-of.... .jpg files in the library without confusing it

calibre always uses the file named cover.jpg, you can store as many backups named differently as you like.

good to know thanks.

any chance that when you drop a cover picture onto an existing book cover ( =paste cover action ?) then a backup could be auto-created ( in some future release )

I have often thought it would be nice to have a supported way to store the back cover (and possibly insert it at the front of the book after the front cover). The back cover of many books has useful information about the book.

Whether there could be any way of extending this to support alternative front covers I am not sure - it would also be a nice feature.

where would you download the back covers from though ? I don't think I've ever seen an embedded back cover in a purchased ebook

Probably Google images. It is quite easy to find back cover images on the internet for many books if you go looking for them.

I've seen them, though not often.

If you find a back cover image and you put it in the book folder as say backcover.jpg and then you move the book to a different library or you rename the book etc then the file will be gone.

Also Check Library will report it in the Unknown files in books section.

You could put it elsewhere and insert a link to the image into Comments - but a subsequent download of metadata that included Comments would lose the link - although you wont lose the image itself. If you put a link to it in a custom comments column you shouldn't inadvertently lose it.

In my experience you can add one additional image by adding its an additional format of type 'jpg'. If you do that Calibre knows about the file. However the approach is not extendible to more images unless you store them in an archive format.

I'm not sure what you mean by "an additional format of type 'jpg'".

As BetterRed points out, if you move a book to a different folder all unknown file types are gone.

This means that "cover.jpeg", "cover.bmp", "cover-1.jpg" are gone. I learned this the hard way.

You can add one format of each filetype to the database; it is not limited to recognized ebook types. Using the usual add format to book (in Edit Metadata) you can add a jpg as a recognized format.

If you use jpg and jpeg, you can probably have two images, as both are valid jpg exensions. You can add a bmp, png, gif, whatever you like. Even .lnk and .url -- BetterRed knows all about this.

Using fake extensions like .jpg1 .jpg2 will also get tracked, but those extensions won't be recognized when you try to open them. You'll need to rename or associate the extension manually.

The rule is, one of each file extension per book record can be added into the database. And then calibre will track it.

Hi eschwartz,

Learning something new is a great way to start the day!

I'm loathe to recommend creating faux file types and OS level associations thereto for the following reasons

• I did it for pdf's but one of my pdf tools didn't like dealing with .pdf1 file types
• If you need to do a windows reinstall you'll likely lose the faux file type associations
• If you decide you're bored with Windows Picture Viewer you want to use the new 'you beaut wunderbar image viewer' then you have to edit the faux extension associations.

And let's face it most users would no more know how to create a new file type and associations than they would know how to fly on a broomstick

You'll notice I didn't say I recommended the idea!

But it would be irresponsible of me not to acknowledge the possibility.

re: the file handlers not being happy. Well, as linux users that's not such a problem for us! So I don't have to worry, which is the important thing. Just joking. I have a linux installer for everyone...
