Can't pin to Pinterest from my page.

Are there any fix to enable visitors to my page to pin my photographs to Pinterest. Here’s the link to my page: https://louisvorster.co.za/

I added the “AddToAny” plugin, which works well for sharing with a lot of the social networks, but unfortunately not to Pinterest. I actually discovered a little workaround; if you click on the portfolio you want to view, and then quickly on the “pin It” button in your browser(if you have it installed), before the portfolio can open, then it gives you opportunity to pin a photo.

thanks
