Can I do this?

[Sonic_16]

Is it allowed by copyright laws to take sprites from other games and put them in Civ3 ? Or other pictures even if they don't have a credit on them? I would like to download some of the other graphics from the forums, but I wanted to know which ones were legal first?

Thanks
