There are two types of "pins" on Pinterest. You as a user can upload your own images, or you can pin a photo from a website. If you're pinning from a website then all someone has to do is click on the photo on your board to go to the website where you found the photo to pin. So, if you find a recipe on my pin boards you like, then all you have to do is click on the image to go to the website I found it at. Sometimes these websites include instructions and sometimes they don't. Hope that made sense!
