Copyright

Well someone asked a while ago where to get my skin from one i made.
I told them they cant ge it from anywhere as i made it anyway they said il just right click and save etc which i said they can not do as its copyrighted.

Well today after a while someone came on and said you can not copy right anything without paying for it
Im sure this isnt true and if you make a graphics they have to ask your permission to use and edit them?
Or am i wrong?

Here is some information that may be useful, in other words as soon as it is posted and you say it is copywrited then it is, but if you want to sue someone for use, then that is another matter...*shrug*
