Let's suppose another tog accuses you, incorrectly, of theft of a copyright image and use on a site such as this.
How can you prove the said images were your own?
Also is it possible in this day and age of advanced technology to trawl the net for any of your own copyright images that may have been stolen?
Once found of course, I'm perfectly aware that it is probably uneconomic to prosecute. I'm also equally aware that to inmitate or steal is a perverse form of flattery, so although I'd be annoyed if someone stole without asking, I am aware that it does happen, probably quite regularly.
