Don't be sorry Mark - just STOP IT
Your shots of late are nice, but no-one is going to 'Print-screen' a copy to be useful as a 2 1/2" tall printed image
In this one, although it's pretty good the sky is bland and banding too, so why would anyone want to steal it?
If you're really worried about stealing images, do as Joe Cornish and others do and show them at 600px or less - (without a watermark) as no-one will EVER want a 2" print however cracking the shot is
