Yes they're full of it
But, for the record, the minute you create something, you own the copyright to it. If you take a photo, then you own the copyright for that photo. No one can use that photo without your consent.
Now you can give/sell that right to another party, or allow its use for a specific circumstance. Somewhere in the terms to use this forum, there is probably a clause saying that you are granting WDWMagic the use of your submissions. I got tired of looking for it, but here is the statement from another forum:
"MousePlanet shall be entitled to unrestricted use, including the ability to create derivative works, of the Comments for the full term of any of your rights that may exist in the Comments for any purpose whatsoever, commercial or otherwise, throughout without compensation or royalty to you. This license is irrevocable."
So even though you own the copyright to anything you write, when you submit it, you are granting that right of its use to another party. I take real estate photos. When I take a photo, I own that image, and am granting its usage to the company I contract with.
There are restrictions on how photos can be used. For instance, having the pictures of those "lovely" people posted here is an editorial usage, and shouldn't be a problem. But if you were to print up shirts and SELL them without a model release, you could be opening yourself to trouble. Think of it this way. If a newspaper photographer takes a photo of you drinking a Pepsi on the beach, and it's printed in the evening edition, that's editorial, and fine. However, if Pepsi uses that photo in an ad, they need a signed model release.
Timekeeper holds the copyright to the photo he (if you're a he) posted May 24. If I wanted to use that in an ad, I would need his permission, plus the permission of the subject to use a photo of him commercially.
Patents are a whole different story.
