Copyright and piracy
There’s no way around it: if your images are online, they’re prone to being swiped somewhere, sometime. Every image should be linked back to its origin, so you can consider a pin as an image in a magazine. You have to make a judgement call on the benefits and the risks.
You can hunt down your images by using this url: http://pinterest.com/source/yourwebsite and replace yourwebsite with your own URL.
