I know I would be interested in knowing how and where my images are being used. I thought many of you might also be interested. I have found that if you run a search for:
"Photo courtesy of Dreamstime" (In quotes) you will find quite a few links to pages that have used images downloaded here. One site in particular keeps showing up and it is the , "How Stuff Works", web site. I found a treasure chest full of Dreamstime images. Here are just two. There are many!
Here's a link to the site, copy and paste it or just search by the name of the site. How Stuff Works.
