It seems that here in the UK, the government is about to amend copyright law by stating that any published image that appears without copyright identification (i.e. a photographers credit line) can be treated as "orphan works". In other words, once an image has been published without an author's byline, anyone can "lift" it and re-use it without being bound by copyright issues.
It would seem there has been collusion here between major publishing empires and the government, and it should alarm all professionals and semi-pros who rely in part on the syndication rights of their images for an income. It is now imperative that photographers submitting images for publication, should make it clear that a byline is mandatory upon a picture being published.
