Sorry, that mod was deserved. Copyright law is complex and require some research. @Dominic gives great advice.
Copyright law changes with the way you use the image/media. If your intention is to make a profit, you need to be much more careful about how and where you use copyrighted works, and get proper permission. Artistic or reporting purposes are treated differently by the law.
From copyright.gov:
How much do I have to change in order to claim copyright in someone else’s work?
Only the owner of copyright in a work has the right to prepare, or to authorize someone else to create, a new version of that work. Accordingly, you cannot claim copyright to another’s work, no matter how much you change it, unless you have the owner’s consent. See Circular 14, Copyright Registration for Derivative Works.
How much of someone else’s work can I use without getting permission?
Under the fair use doctrine of the U.S. copyright statute, it is permissible to use limited portions of a work including quotes, for purposes such as commentary, criticism, news reporting, and scholarly reports. There are no legal rules permitting the use of a specific number of words, a certain number of musical notes, or percentage of a work. Whether a particular use qualifies as fair use depends on all the circumstances. See FL 102, Fair Use, and Circular 21, Reproductions of Copyrighted Works by Educators and Librarians.
Good luck
