Thanks for submitting this!
Do you have an example of a v3 book that fails this check? I'd like to add it to the test suite.
Never mind. Those books are produced by my company, I think their opf files should be updated to follow the epub spec. I'll close this pull request. Sorry for the noise.
Many version 3 books still use old version meta element, which make cover image reading fail
