Add a Pin It! button over your images! CSS3 Fade In/Out with the ability to upload your own custom image!
Took a while to get this set up because the initial instructions didn't work immediately. Thankfully some other members in this help forum gave out a trick to get my custom image uploaded! Great plugin seems tricky to find help from the developer.
I started installing it on all my sites that use photography and images, such as this recipe site. It's only on my post pages (for some reason it doesn't work on my home page, but I think it's due to my page setup and/or theme, because it works on my other sites); but overall I'm very happy with it.
