Years ago (early 1990s) when I started off as a designer, I was advised to print copies of any designs, seal them in an envelope and post them to myself by recorded delivery so I would have proof of the date should a copyright dispute go to court.
Does anyone know if this is still a sensible thing to do, or are there now so many other ways of proving the date of an image, particularly on the internet, that posting a hard copy is no longer necessary?
Basically I'm asking if it's safe to put images of new designs onto my Facebook business page, or if I need to do the post thing first? I realise that it's unlikely that anyone would copy my designs exactly or that I'd be able to afford a court case if they did, but I'm just interested to know what designers do these days.
