The good news about this Pinterest update is that you won’t have to do anything differently to include the attributions on Flickr, YouTube, Vimeo, and Behance. Using the “Pin It” button from Pinterest on a page will automatically fill in the attribution information for the image or video you’re posting. Those details cannot be changed by a Pinterest member, so credit will always appear when pinning on those platforms.
Even though the text associated with the original image does automatically appear in the caption part of a pin, as you can see in the image above, it doesn’t have to stay there. You can add, edit, or delete any portion of the text before pinning and the credit for the pin will still appear at the bottom on the Pinterest site.
Pinterest is being very thorough with these attributions. The team said credit would be applied retroactively to as many images as possible that were shared from those platforms prior to the launch. According to the Pinterest blog post announcing the change, the team will be able to add the attribution even if a Flickr photo is pinned from a website or a blog with the image embedded.
