Agree with Loree.
I just checked three of my images, and there were many links back to many of my original pages / usages of the images.
But I do have a question. In the google blog, it says this:
"People looking for images on Google often want to browse through many images, looking both at the images and their metadata (detailed information about the images). "
In checking my images, I could not find a way to display the detailed metadata as stated in the article. How is this done?
