Except that a very significant portion of newtype isn't manga. In fact, rather than saying that a portion of it isn't manga, it's more accurate to say that only a portion of it is manga, since most of the magazine is in fact not manga. Additionally, from what I can tell, the majority of Newtype covers don't have pictures of characters in the manga they serialize; they have pictures of popular anime and manga at the time. A google image search for the Japanese serialization name, ニュータイプ , returns a lot of covers featuring characters from the Suzumiya Haruhi franchise, as well as others such as K-ON! and Kissxsis, which have never been serialized in Newtype.
To make an analogy, let's take an essay. If you take an essay about censorship that passively mentions the book Nineteen Eighty-Four in one or two places, and let's say that one of these places includes a quote. You wouldn't call it an essay on the book Nineteen Eighty-Four. Sure, it contains a quote from the book, but the majority of the essay is not about the book Nineteen Eighty-Four. Therefore, an instructor who had told you not to write an essay on Nineteen Eighty-Four would probably still accept it, especially if you've got stuff not related to the book in it. They might ask you to remove that reference, though.
This is a very different situation from writing an essay about Nineteen Eighty-Four that references some other nonfiction source on censorship. Your instructor would have you re-do the whole essay.
Similarly, the equivalent of the references, which in this case would be the single chapter of manga that they serialize in each issue, should be removed from Gelbooru. However, the majority of the magazine should not, including the cover. Compare this to serializations that feature primarily manga, such as Weekly Shounen Jump. Since the cover on a magazine like that would be a manga cover, it should be removed.
