So I uploaded this image I found on Deviantart from this artist named AtteroAmore (I asked him if I could upload the image and he gave me permission, as long as I gave him credit)
But when I tag his name as an artist, it doesn't come up as him being an artist (I clearly expected that)
So how do I get his name under the artist name, so I can give him credit?

art:atteroamore
