Re: New Book about TOS: These Are The Voyages
This issue has the potential to become a long form birth certificate scandal in fandom. If the published images in question are individually credited as "Courtesy of startrekhistory.com", then that suggests the author or publisher has some type of document signed by Star Trek History allowing use for publication. Going to a website and downloading images which you then publish are not typically considered as "courtesy of".
