Roel, she is lovely and so is her dress. I am sorry that happened to you.
I have a Flickr account. About 4 years or so ago, the first pic I took that I was really proud of showed up on one of those Russian Porn sites. And it was a yellow rose, for gosh sakes! They cropped the heck out of it and the resolution was awful, but use it, they did. It also made the Asian sites.
And it happened again recently, this time with a silly self portrait, only it was posted on a blog motivated by hate (why, I'll never know). That prompted me to make all my Flickr images private and available to only Friends and Family. I want to have my own Photography website, but fear the hate monger will find it and assault that one too.
It really bites big time to screw around with your life like that.
All it takes is a "right click". Nothing is safe. All the warnings in the world won't stop someone from stealing an image if that is what they want to do. The only alternative is to not put anything on the web.
You know... I think there is a way to code your gallery so that pictures can't be copied/pasted. I'll do some more research but I have noticed on some sites you can't even right click on an image.
ETA: Nevermind. All a person has to do is print screen and then crop it in PS. I just don't understand why anyone would do that....
Super I am so sorry that happened to your wife. It's despicable. It makes me truly sad.
