Excellent and true!
Paranoia doesn't mean you are not followed and images get stolen and misused not without the intention of somebody making it to happen.
FYI: Dividing by a fraction or decimal increases your number. Although I love the idea of the division bar (and it looks nice in your equation), you should actually multiply by 50% if you want to fade the logo. Unless you actually wanted the logo 150% opaque?
Never used water marks on my posted photos, only my name in the frame.
@Anonymous - I guess we have to work on our math. Thanks for the division tip :)
I would say Watermark = don't steal from Scott Borne unless you want to get sued....LOL
