Add pin-it button to php generated slider images

I’m working on customizing a theme (fallen-angel.gozawi.com) for a blogger/stylist who wants to be able to place a pin-it button on to all of her images, including the portfolio images. I can’t seem to figure out how to make this work because the images in the portfolio are automatically populating instead of being posted within the content. Any help?

Thanks!
