Did a photographer send you an email complaining that you are stealing their photography?
Did the message read something like this:
Subject: You're not allowed to use my images for yourwebsite.com without my permission! It's illegal! This is a lawsuit against my rights! You must remove these images NOW!!!!
There is such phishing spam that has been going around for some weeks.
We get several of these fake warnings every day, each time with a different name for the photographer!
The best thing is to simply ignore them.
