I searched and SEARCHED everywhere for a way to display an image at a small size on my blog, but then allow readers to pin the full size image on their pinterest board. I couldn't find anything. JQuery for pinterest was highly recommend for a pin it app,so I emailed the author about my dilema. He said he was working on it. Once it was done, he emailed me to let me know of this extension.
IT WORKS PERFECTLY! Now, I can display images the way I want on my blog and my readers can pin them to their full size (which I have optimized for Pinterest)
Highly recommend this add on.
