I recently tested the Pixelpost plugin from Jay Williams, to upload images directly from Lightroom to Pixelpost blogs. Since the plugin is not yet supporting Lightroom 3.3 I made it compatible. Taking just 10 minutes since two methods became deprecated, that must be exchanged. If you like to get it running just download this lua script file to your lightrooms \Lightroom\Modules\pixelpost.lrdevplugin folder – for Windows user (beneath AppData folder) and restart Lightroom.
