Social Share Buttons for Images

Hi!

I am designing a site for client and part of the site is encouraging visitors to share images on the page to their social media sites.  The only platform Squarespace has integrated is Pinterest.  Does anyone know how to do the same thing for Facebook, Twitter, and Instagram?  The site hasn't launched yet, but I've added a screen shotsand if you're interested, just ask for the site and password. 

Thanks!

Jane

What happens if you add a social media block under each image?

Or you could make each image a blog post, and enable sharing. 

These approaches would work best with templates that show the separate icons and not just the basic sharing image. I wish all the 7.0 templates offered that.
