Sorry I was blunt, but really, it's not hard to get things copyrighted and it's a really good idea to do so.
General Information
Copyright is a form of protection provided by the laws of the United States to the authors of “original works of authorship,” including “pictorial, graphic, and sculptural works.” The owner of copyright in a work has the exclusive right to make copies, to prepare derivative works, to sell or distribute copies, and to display the work publicly. Anyone else wishing to use the work in these ways must have the permission of the author or someone who has derived rights through the author.
Copyright Protection Is Automatic
Under the present copyright law, which became effective January 1, 1978, a work is automatically protected by copyright when it is created. A work is created when it is “fixed” in a copy or phonorecord for the first time. Neither registration in the Copyright Office nor publication is required for copyright protection under the present law.
Advantages to Copyright Registration
There are, however, certain advantages to registration, including the establishment of a public record of the copyright claim. Copyright registration must generally be made before an infringement suit may be brought. Timely registration may also provide a broader range of remedies in an infringement suit.
A work is copyrighted while online, but getting it registered (which is what I really meant, sorry about the confusion) is really REALLY beneficial just incase theft does occur. Hell, I'm going to register what has been leading up to my thesis just to be safe. Maybe I just assumed most artists know these things, but I learned this practicum and I'm guessing a lot of artists never had a practicum class. People should know how to protect their work, however, and I think if artists are going to be "professional" about it, they should do what they can to protect their work whether that thing passes or not.
I sincerely hope that this never does pass, but if it does, chances are my work will be protected and I will probably have taken down any images off of the internet that are not actually on my website.
