Re: Copyright Infringement
"You don't need to have registered your photograph to claim copyright. By law you have up to 12 months to register the copyright on any work you create. Its called common law copyright. The act of creating any work that is allowed copyright protection under the law starts the clock on the common law copyright. In other words, copyright is kind of automatic."
That's so bad it's "not even wrong".
Yes, the creator of an original work fixed in a tangible media (including digital images) has an automatic copyright in those works.
In the US and other signatory countries to the Berne Convention, Copyright is given to the author for their life plus a certain number of years (far too many, IMO). This does not change if the image is not registered.
A "published" image must be registered (at least in the US) within 3 months of publication to maintain the full suit of remedies including statutory damages and attorney's fee plus court costs. You would still hold the Copyright past the 3 months but it wouldn't be worth a bucket of spit unless you normally get paid a ton of money for each one of your photos/works. You could only sue for the amount you can show that you normally charge for a similar image or what you charged for the one in contention.
As an aside, in the US Copyright is Federal law so it is only heard in Federal court. It is not heard in State/Municipal courts. This means that attorneys are going to be involved. You could try to argue a case on your own, but a judge may not be pleased and you could easily lose on procedural grounds.
