Drew, copyright is not as clear cut as some people think... nor does it protect you as well as it is suppose to. Here in the US, the moment you create a picture, you have a copyrighted image. It's automatic. The problem is, that that copyright is like putting a suitcase lock on your front door. It will keep the honest people honest, but nobody else. The reason is that to protect your copyright, it costs money... lots of money. If someone steals one of your images and uses it for something and you find out and they refuse to pay you for it's use or to even stop using it, all that leaves you is taking them to court... Federal Court, which is not cheap. I've been told by copyright lawyers (Intelectual Property or IP Lawyers) that taking a case all the way through to a judgement could run up to $50k or more. Just to get it into the front door of the court can take up to $10k. And if you win, the judgement against them might not even be enough to pay off your legal fees. So most people have a choice, spend a lot of money to sue someone or walk away from it. I've had it happen to me and though my principles said to take her to court, I found my principles didn't have enough money to do it over the picture she stole and used. I did get her to stop using it, but that didn't really make me feel a lot better after she had gotten away using it in two national magazines and refused to pay me useage fees.
But there is a way to get the copyright law to work for you and protect you all the way... that is to register your images with the copyright office (Library of Congress). You don't need to register your images to have them copyrighted,
BUT there is one very special benifit to having them registered... if someone infringes on your image and you take them to court and win, they get to pay ALL court and legal fees for both of you. And IP Lawyers know this and will try to get their clients to settle long before it gets to court. And the chances are very good that they will when they find out your images are registered.
Registering is easy and cheap. The short of it is, that you can register as many images as you can fit on a CD for $35. I registered one CD that had several thousand screen size jpeg images on it. And I've done 4 or 5 CDs so far of images. I chauked up the infringment against me as a wake up call and a boot in the back side to learn about copyright (I didn't know near what I thought I did) and get my images registered.
There are two classifacations of images to register... Published and un-published. Published images are those that have been sold, rented, leansed, or what ever that has made you money and a few other criteria. It doesn't mean that you have had them on your web site or shown them to people or even had them published (as long as you didn't get paid for it). For published images you have 90 days from the day they are considered published to get them registered. After that you don't get the special benifit. For un-published images, you can register them anytime (up to 90 days after they get published) and still get the special benifit.
You have to send in these two types of images seperately on different forms and pay $35 each. I just register all of mine as published (it's up to the author to determine if their images are published or not if they don't meet any of the other criteria) so I can put everything on one CD and use one form. It's not to save the money, it's just easier.
When you send your images in, the registration starts the day they receive it, so I just use delivery conformation and print off the information from the USPS web site that shows the CD was delivered. I add that to my copy of the form and CD that I keep in my files.

It's worth piece of mind and the extra protection.
