First time Calibre user here... and trying to understand if Calibre is able to truly remove cover images embedded into various mobi files I have or not.

After adding some mobi files into Calibre, and then editing metadata, none of the changes are written out to the file that I actually added to Calibre, but are instead (I presume) saved in some kind of Calibre library database or index or something? The only way I see to write the changes out to file is by using the "Save to disk" feature... which appears to write the file out to a new file...

While title and author changes appear to be written out to the new file... the 'original' cover image(s) are still all present and not actually removed. Any 'new' cover image I add in Calibre is saved to a JPG file, and not embedded in the mobi file.

I want to achieve TWO things:

1.) Make sure any and all 'existing' cover images embedded in the mobi file are stripped out...
2.) Make sure any 'new' cover image I add in Calibre gets embedded in the file I Save to disk...

I will also be 'converting' some of the MOBI files and saving them as EPUB along with newly modified MOBI, as I want to put the same books on my wifes iPad as well as my kindle... and while I am not familiar with EPUB format conventions - I'm assuming it's valid to want the cover image embedded into resulting EPUB file that I want to save off to disk as well...

Can someone offer guidance...?
