I'm currently running this widget as well as a category gallery widget on my Recipes page of my site (http://www.cupcakesandcoffeebreaks.com/).
Even though I've specified in the widget settings to not display the Pin It button on images under 300px by 300px, it still displays on my category gallery, which is inhibiting users' abilities to click through the gallery to my actual recipes.
The weird thing is, if you refresh the recipe page so that it loads a second time, the probably usually disappears (or sometimes remains, but only on certain images).
Why is this happening? As far as I know, it shouldn't be appearing on my gallery thumbnails.
