A question from a colleague: I have a question with Lightroom plug-ins. I’ve downloaded and installed several (MobileMe, PhotoShelter, Facebook, etc.) and they show up OK in the Plug-In Manager, but fail to show up in the Export dialog?
My Answer: look in the Export To: menu at the top of the Export window. You must choose the web service as the destination first. Then the options for the plug-in become available.
