Might it be the case that your program doesn't do jpeg compression on pasted cover images?

The altered epub file didn't show up in my venerable FBReader any more and was bloated from originally 7 MB to ~10 MB. Calibre did read it and displayed the new cover.
I extracted the contents and indeed, the cover file was a PNG with .jpg extension.

epubs also disappear from FBReader when I only edit metadata, like date > edit date's event type (to publication) > (change content). Too bad ;-(
Too be clear, I always restart the reader after making changes and the books vanish from FBreader's library view.

(platform: Win7 x64)
