copyright laws protect materials whether the owner cares about protection or not, keep this in mind.
actually, not at all.
copyright infringement is a civil action in both europe and the states. and since russia, singapore, china and the likes have next to no copyright regulations, it's extremely unlikely that, say,
lex talionis is appliable for the case in point.
a civil action means the breach of law cannot be verified and prosecuted automatically by the public authority: the legitimate owner needs to file a lawsuit
and offer proof of economical loss - of any kind - in order for the bothersome activity to cease and, in case, for him to be refunded.
this is why
freeware material has technically no chance to be awarded protection over the net, as long as its qualities of "being free" and the identity of the author are preserved intact.
to cut a long and boring story short, i think it is safe to say that you can put that pic anywhere you like on the internet, as long as (i) you don't claim you did it; (ii) you specify that "all material is the copyright of the respective owners"; (iii) you do not evidently alter the characteristics of the pic
and still claim it's the original.
specifically:
i. is a remote chance anyway, plus you say that's a popular drawing so you don't need to write "I DID NOT DO THIS!" all in capitals.
ii. is a simple disclaimer, and you
in no way need to find out the name, marital status and home address of the actual owner. that is really ludicrous as it would be so impractical that people had to do a long research for every single thing, and somehow figuring out by themselves which among a bazillion manufacturers is the real owner of the rights of each brand name.
iii. just stick to the safe concept of not claiming anything false and it's gonna be alright. never care about using copyrighted material in a hyper-critical, potentially offensive context. you can do it. it's called freedom of expression and the corporative idea of signing a 400-furlongs long license agreement for every piece of crap a supposedly "creative" author has made
still hasn't taken that away.
anyway, no one is going to sue you, no matter what you do. if you really really make a mistake and someone notices they're gonna tell you to take the material offline. unless you're sure they're wrong, you then take it offline (or change server) and everything is fine again.
the reason why companies do not take it out against "ordinary users" is not that they can't find you (they can) or they don't care (they do): it's that even if they were to take you to court you wouldn't be able to provide an amount of money that has any relevance whatsoever to them.
