I've found an issue with inserting covers. I am surprised I never noticed this before. The thing is, I don't want the cover image resized to be 775 lines. That means the same ePub on say an iPad won't look good as it will be too small. cover images do work on a Sony if they are larger then 775 lines. Can this either be removed or made yet another check option to resize?
