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>.
