I'm talking something like this:
http://www.airliners.net/usephotos/

There's a company using two of my photos which I'm assuming they've found off this website (one of the photos isn't on a.net) without my consent. They've used them on their website, www.denverairconnection.com (top thumbnail and bottom thumbnail, left side), as well as on two brochures they were passing out at an airshow on saturday (I have copies of both).

I'm not sure if I have the resources to fight it if jp.net doesn't have the legal usage policy b/c it would be alot harder to prove that this site isn't considered public domain.
