I'm trying to add a Pinterest share button to our AddThis implementation on pages like http://www.biddingforgood.com/auction/item/B4GItem.action?id=172656223 (the icons in the middle of the page, not the ones in the upper left), and am having trouble. I add <a class="addthis_button_pinterest_share"></a> and also specify the og:image meta property, and while the image displays, clicking on it does nothing. I don't see any JS errors when I click the image and the other icons (FB, Twitter, LinkedIn) all work fine. Is there anything I have to change in my config or something? Update the JS file I'm referencing? Any guidance would be appreciated because I spent a few hours today trying to look into this and came up empty.
