Changing Covers

denmarks · 08-18-2011, 05:58 PM

I had many MOBI files with no covers. Calibre was displaying the first page as the cover. I used the "edit metadata" to locate and create covers. I then used "convert" to create new MOBI files. I later removed the originals.

I then made copies of the MOBI files and added them to a Kindle library. The Kindle for PC program showed all the covers that I added.

I then tried to replace a few of the covers that I added. I used the same procedure I used originally to edit and then convert. Calibre shows the changed covers.

I deleted the old ones from the Kindle library and added the new ones. The covers did not change. I tried it a few times with the same results.

It seems as though once a cover is added to the metadata it can't be changed. Calibre must be showing the jpg that is its library. What can I do to resolve this? How do I remove the metadata version?

I tried using the "delete cover" button but that only removes the jpg. The converted file still has the old cover.

For MOBI, you'll need to reconvert the file for the cover to change.

If you want to change the cover in a MOBI file you need to run a conversion (even if it is MOBI->MOBI).

I did reconvert. It creates a new MOBI file and saves the old one. The new file did not have the new cover. I viewed it using Kindle for PC. Even when I deleted the cover and reconverted the old cover remained.

Kindle for PC caches covers. Use the calibre viewer to check the current cover in the file.

Is there a way to clear the cache in Kindle for
PC? I tried uninstalling and reinstalling but that did not work.

Does Calibre show the JPG in the calibre file or is it the actual metadata?

NEVER MIND. I deleted the covers from the cover folder and it recreated the correct ones.
