Let’s say, I’m an entrepreneur who sells widgets. To market those widgets more effectively, I take attractive photos of them and post them on my website. A widget enthusiast who is unaffiliated with my business starts a pin board on Pinterest and “pins” one of the photos from my site.
For this example, let’s assume that the enthusiast “pins” the image directly from my site, which means that the “pin” will link to the page that displays that photo on my site.
The pinning process involves making a copy of my photo; Pinterest generates a smaller version of images, and uploads them to pin boards on that site. Pursuant to the copyright law referenced earlier in this article, doing so constitutes “reproducing the copyrighted work,” which would be in violation of my exclusive right to do so as the copyright owner. Ergo, Pinterest and the widget enthusiast would be liable for copyright infringement.
