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>.

Shared Counts – Pinterest Image

Use a separate image for sharing on Pinterest

codefish

This plugin adds your favorite pins much like the pinboards on Pinterest. It uses the original thumbnails from Pinterest itself. The plugin aims to have the same look and feel as the pinboords on Pinterest. To improve your site’s performance, the pins are cached every 15 minutes.
The Pinterest Pinboard can be used as a widget in your sidebar or on any page using the shortcode.
