My Contra: Hard Corps sprites

[Eckles D. Fum]

I have a question... There's this guy that placed Browny's sprites on the sprite database, but he's missing like three or four sprite poses. Let's say I take them, update them, place them here and on my tag, I give him credits. He's not asking for permission, or credits, but to me, if I don't give him credit for what he did, it would be wrong. My point is can I do that? I mean, I'm not stealing, or taking credit for work I didn't do...
