The Carol Corps, they have a bunch of cool images, fan art, and all-around neat things centered on their love for the current Captain Marvel.
They even have a link to cool papercraft models of Captain Marvel, Black Widow and Sharon Carter.
The Carol Corps also have a cool deviantArt page where they collect submissions of fanart of Carol Danvers as Captain Marvel only. No Ms. Marvel (or Binary, I suppose) imagery please. That page is also worth checking out.
