This add-on for <a href="https://wordpress.org/plugins/shared-counts" rel="ugc">Shared Counts</a> allows you to share a different image on Pinterest.
Shared Counts uses the post’s featured image for sharing across all platforms. But given the unique display of images on Pinterest, it’s useful to specify a separate, Pinterest-only image that’s formatted for that service.
This plugin will only work if <a href="https://wordpress.org/plugins/shared-counts" rel="ugc">Shared Counts</a> is active. It does not work with any other social sharing plugins.
Customization 
By default the plugin only applies to posts, but you can <a href="https://github.com/billerickson/Shared-Counts-Pinterest-Image#customization" rel="nofollow ugc">add support for other post types</a>.

If you’re looking for an easy way to pin images in your blog posts and pages, this plugin will help you with that. It highlights images and adds a “Pin it” button over them once the user hovers his mouse over an image. Once the user clicks the “Pin it” button, the plugin shows a pop-up window with the image and a description. Everything is ready for pinning, although the user can alter the description.
The plugin allows you to:
<ul>
<li>choose from where the pin description should be taken </li>
<li>choose which pictures shouldn’t show the “Pin it” button (using classes)</li>
<li>choose which pictures should show the “Pin it” button (all images, post images, images with certain class(es))</li>
<li>choose if you want to show the “Pin it” button on home page, single posts, single pages or category pages</li>
<li>disable showing the button on certain posts and pages</li>
<li>choose transparency level depending on your needs</li>
<li>use your own Pinterest button design</li>
</ul>
Once you activate the plugin, it’s ready to go with the default settings – button appears on all images within the body of your posts/pages that aren’t marked with “nopin” or “wp-smiley” classes.

jQuery Pin It Button for Images

This plugin is easy.  EASY. To use.  In less than 5 minutes you can declare which images on your site via a simple CSS selector string.  Anyone with some jQuery or CSS education will be able to master this in minutes.  I'll keep this tool handy on other projects.

Kudos!

Super easy and simple to use
