Abuse of Image

I am looking back at the picture I posted an hour ago. I wonder if I am abusing this woman's image. There are two arguments. The first is that she posted her picture on the internet. She should know that when you post something like this you are releasing it to the whole world. The second is that she put her picture up for a specific purpose. I had to dig pretty deep to find it. I am out of bounds to use it for my weblog.

I want to know what other people think. How would you feel if you found a picture of yourself on someone else's weblog? Someone you do not know?
