It is quite possible to describe artists and art, and talk about it without showing it, much like authors can be covered without quotations. Most of the fic author pages I've come across on fanlore (like for example the DS author profiles) don't quote anything from the fic but rather quote reviews and feedback to the fic, yet almost all artist pages show a whole gallery of art without talking about any of the pieces. I assume that is because quotations aren't pretty but pictures are and it's no almost work to include the images you grabbed, but it is effort to say something about an artist.
Further, there almost no articles about individual pieces of fanart that discuss that piece of fanart specifically, while there are some pieces about individual vids and stories. Actually I can't think of a single one article about a single fanart picture. Individual pieces are rarely even discussed in any way in other articles. Fanart is used to show a zine (often many, many art pieces from a single zine), to show a trope, or in galleries gathering everything from an artist that found its way onto fanlore.
I have started several articles covering art genres on Fanlore (like the Still life or documentation/ephemera article) and managed to be fairly comprehensible (I hope) without including images, and even if an image was needed to cover a whole genre it is unlikely that you absolutely need the fanart of an artist who objects, and couldn't use art from an artist who is fine with it.
