I tried using the built-in Photocrati sharing buttons but found them limiting as to location. The Jetpack version was better but was still very limiting. The Jetpack Sharing butttons shortcode sounded like the answer, but when I installed it and placed the [jpshare] shortcode in the page, nothing happened. Only when I checked the “Show sharing buttons” checkbox on the page edit screen that was presumably placed there when I activated the Jetpack Sharing (not the button shortcode plugin) did I get something. However, I not only got the Jetpack shortcode Facebook button, but also the standard Jetpack sharing button for Facebook. When the “Show sharing buttons” is unchecked, both disappear.
