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>.

This plugin allows you to place a widget on your sidebar that fetches the most recent contents of a Pinterest user’s RSS feed and displays the corresponding thumbnail images. You can choose whether to show the description below the image, and you can set the height and width of the thumbnails to fit your theme. You also have the option of showing 4 different sizes of the official “Follow Me On Pinterest” button below the list of your pins.
You can also use this plugin from your theme templates, to display images lists anywhere else on your blog and you can easily give them a fixed size or a maximum size with CSS styling.
Starting with plugin version 1.3, you can also add a list of thumbnails of your Pins to a post or a page in the editor using the shortcode [prw username=”Your Pinterest Username”]. (See FAQs for instructions).
Version 1.4 adds the capability of showing pins from a specific board in the widget or shortcode, rather than just all of the latest pins from a specific user. (See FAQs for instructions).
Note: This plugin is heavily based on the Image Feed Widget plugin created by Yorik van Havre (https://wordpress.org/extend/plugins/image-feed-widget/). As of version 2.0 it also utilizes the jQuery NailThumb script for image resizing (http://www.garralab.com/nailthumb.php) and no longer utilizes the timthumb.php script.
