Hi All,
We have added social sharing buttons to the bottom of your gallery and image pages alongside the vote and comment links. If you would like to stop seeing the buttons, you can disable them on your account settings page - http://www.pbase.com/account?view=plugins
By default, we turned them on. If we had them off by default, it would take forever for people to realize they could enable them and start using them.
You will see a +1 icon to use Google's +1 - http://www.google.com/+1/button/
There is also a facebook "like" button, which lets you share an image or gallery with others via your facebook wall.
If you are viewing your own images and have the social sharing links turned on, you will also see a "send" button. This will let you send a link to the image/gallery, along with a message, to a mailing list that you specify. We thought this would be useful for letting friends and family know when you have uploaded new photos to PBase.
Enjoy!
-The PBase Team
