Adding Pinterest Plugin to Site

I am having some issues trying to get a Pinterest Hover icon on all my images on my website. My goal is to have the ability to share directly on Pinterest. I have tried multiple Pinterest plug-ins but I can never seem to get it to work properly. I’m thinking it has something to do with how the images are formatted on my website. For instance if see on my site, the images shows you a magnifying glass to expand the image when hovering over it. I’m thinking this is somehow disruptive when the with the Pinterest plug-in.

I would appreciate any suggestions you might have. Can’t even begin to tell you how long I have been spending on this.

Plug-in I’m trying to install.
