What are peoples thoughts on "stealing" In the gallery?

Stealing of any kind is morally wrong; it being online doesn't make it any different. If you edit something a considerable amount then re-upload it with specific reference to who made the original, I don't see a problem with that, but people who post exactly the same thing as someone else, in my mind are like musicians who do nothing but covers - I think they don't have the creativity to make their own.
