I liked this plugin a lot, but the Pinterest button on the sidebar was not pulling up all images in a post to pin on pinterest, it just took the first one. The Pinterest button on the bottom was working fine. I was trying to put a top bar with the functional pinterest button but the plugin would not let me arrange the Pinterest button towards the front of the row of icons.
I ended up switching to Shareaholic. I don't have a floating sidebar anymore, but that's fine - I now have a great pinterest button included in the share icons at both top and bottom of my posts. Their Pinterest button pulls up all images in a large window.
