The new Google Images
I remember years ago making a bit of money off of google images incoming traffic.
But now, they're not even sending the user off to the source page of the image.
You can just click "View Full Size" and bang, you get the complete image. No need to visit the website of the guy who actually created the image anymore...
I was pretty shocked they went this far with it. It would be a very interesting copyright case.
