I think this is a great idea. I am a professional stock photographer and make my living from licensing images, plus some writing.
This means that the British ISPs will scan every photograph uploaded to their servers, plus all illustrations, designs and text quotations and snippets, compare the usage with the terms and conditions of any outstanding licenses or authorized uses, evaluate for fair use and derivative usages, determine what content is in the public domain, resolve jurisdictional issues, and then if necessary either bill the user and send me the money, or insist that the content be removed.
Wait. You mean this only applies to Hollywood films and recordings from the major music labels?
Oh darn, looks like it is not such a good idea after all
There seems to be significant debate too as to whether or to what extent state law, e.g. a contract, would be preempted by federal copyright law and thus could not be used to establish new de facto intellectual property rights,
@TheBaker Of course the Printoom Inc. hasn't registered the images either
@Nick Indeed it would be interesting to know what they actually think the contract is. If the images are public domain then wouldn't a contract only be with the buyer of the print, not with anyone they gave or sold it to?
