Official (by my definition) = Released by Sega, Nagoya, or 4Kids. It's like calling a doujinshi a canon, official work (implying here that you know the term; it pretty much means a Japanese fan comic that is printed as a book). It's common knowledge that the two are separate -- the main canon and the doujinshi's story. People wouldn't say, "But this picture from the fan manga is official! It went in print!" Do you get my meaning?
I had overlooked that image since I had been undoing your edit, and so I got rid of the last two images which were definitely from the manga.
Of course, if we ever need more clarification, we could get either Bionicle's opinion or oOMellyChanOo's.
That sounds like a great idea! It's always important to give the benefit of the doubt and listen to others opinions even if you don't agree or like it.
Yeah I noticed you did that it's okay though, but we should really put them back. In the meantime I'll some images of Pterosauria Legends manga, a while back I had found the website that had a preview of the manga.
