Its pretty crappy when some one says they ,made your art that you working on for over a month straight .. and that is also a part of a bigger picture.
Its just wrong .. a really bref section on copy write laws..
copywright infringement is punishable by jail time and up to $25,000.00 fine
The law of copyright also applies to the Internet, and so most individual works found there are protected: using Internet text or graphics without the permission of the copyright holder, for instance, is an infringement of copyright law.
