*Would like a plug in to upload pictures directly from Lightroom to Panoramio.*
Please note this is the English sectio of the forum. There is also a Dutch section if you want but here we try to use English as a common language.
Lightroom is owned by Adobe, whereas Panoramio is owned by Google. With Google having it's own image management and editing software (i.e. Picasa) there is limited chance that one of both companies will develop a plug-in for Lightroom that would enable you to do so. But maybe you should ask Adobe.
