Please have a look at http://500px.com/photo/3977429?from=popular. Down in the right corner, theres a sharing box. It looks pretty similar to sharethis. But, afaik, sharethis doesnt have embed or submit for example, and im looking for those options. Does anyone know which plugin is used here? Thanks
Inspecting the source leads me to believe that it is custom work. The images, links and such are placed in the HTML serverside. Only the stumbleupon is pulled from stumbleupon itself. But also not trough some third party service like sharethis.
