This plugin will automatically add Pinterest Pin buttons to all the images in your WordPress content posts.
This is the only plug-in that kept me transferring bethanymichaelaphoto.com from wordpress.com to a self-hosted WordPress site. This plug-in cut off all of my posts and pages when my self-hosted site was up. I deactivated all of the plug-ins to find out this was the one causing all my problems. Please fix this if you want people to use it.
Doesn't seem to be working and it looks like there's no support. I'm uninstalling.
