Pinterest button for Slidedeck Gallery -- 2

Hi, I have a slidedeck installed on my website. ([login to view URL]) I would like to add pinterest pin it button to every image in the slider. Screenshot:[login to view URL] I need every single image to have a pin it button that appear only when mouse is over them. I will create new galleries in the future so this change must be done in a way so if I add a new gallery it will work fine for that gallery as well. Also, when I click to pin-it, I want it to pin that particular image not the featured image of the gallery. If it's possible to make it so this change never disappear even if plugin gets updated, I would be happier, so mention if you can make it that way.
