Looks like we are pretty much on the same page.
I have never inserted another image to conceal a location, only blurring.
I don't have the time or skill to bother.
I also prefer the au' natural look; whenever possible.
I will also preserve mother natures beauty by posting hard to locate, un-adulterated photos and posting blurred, don't-come-here-and-ruin-the-fishing-for-me photos.
I have to warn you now that I feel an urge to include your likeness into one of my future posts!!!
Cheers
