By the fact that winonamalik1d uploaded it to her gallery, she is stating that it's her artwork, since this is an art exhibiting website, and not just a social network/picture sharing webpage, like tumblr, 9gag, facebook, pingterest, etc., and it's copyright infringement by her side; so don't just rant around disrespecting users that tell other people to do the right thing.
doesn't mean it's okay. 1DtrueDirectioner, you might would be suprised to hear but posting work that you have not made it's against this site policy. Even if other people like yourself do it too. It's in the term of service, mate. Don't curse. That's rude. Whose the peasent now?
