I don't get it.. why? You even link to the post yourself, obviously showing that you don't really care what you're doing or acknowledging that it's wrong.
"wrong" and "right" are subjective concepts. Take Paletstine for example: it's okay for Jews to squash palestinian kids with tanks, but not so okay for Palestinian kids.
I hope you don't say that you'd find it perfectly fine if someone took the entirety of your code for your game and added it a few lines to it to make it 'his'.
I'll be happy. Alas my code is perfectly safe, unless you understand expressions like
get FileName |c:[T:@4.utf8 L:@4.ul D:@L.y @Xs] [[T D] @Xs,r]
And then you proceed to combine his piece with another piece which I assume is also not yours.
Yeah. I've taken it from Ultima Online, which I torrented.
frankly the results are quite horrible.
Better than nothing. I'll also try to retouch it.
I mean, look at those skewed, stretched and messy pixels. 
They give general idea, how it should go.
People here would be more than willing to help you out if you make an honest attempt at something like this yourself.
I'm not an artist and stealing is normal - everyone starts with copying old masters.
You're not going to get very far using other people's work even if legal stuff isn't concerned.
I'm not walking anywhere. Just exploring ways to quickly acquire sprites, without paying a fortune for artist work.
Just as a side-note, if you're looking to preserve relations with this artist, stop what you're doing! It's hard for me to think of something I hate more than someone trying to hijack my art and do it "the easy way." Either negotiate with the artist for more frames, hire someone else to make more, or really, anything but this. It's going to look terrible. Low frame rates would be much better than stretching pixels and all the nastiness that you're going to incur here.
I don't have money to negotiate anything and I have no relation with any artists or anyone at all, so I've nothing to lose.
