Each pin on Pinterest has a web address associated with it. Pictures of food will almost always link back to the full recipe. Many products that you see will have more information and even a place for you to buy. Unfortunately, in a world where content can be copied without referencing the original creator, you'll find some dead ends. But often you'll find a wealth of info past the picture, and thanks to new initiatives such as the updated Pinterest article pins, which let you discover and share articles from some of Pinterest's favorite publications, sites, and other media outlets, as well as pin and save these articles to read later, it's even easier to keep track of the original source.
