digital photography techniques | Adobe Photoshop Lightroom 3
I have never used lightroom however any plugin I would suspect they would need to make. We manufacture PHP applications which are web based maybe a little java etc thrown in. Your talking about a proprietary encrypted application installed on a home computer. Therefore if there was some export feature it would have to be coded in by the company that makes the application.
Now just a couple thoughts. Lightroom to me looks like another graphics editor to resize crop enhance photos etc just like the old photoshop etc.
Anyway these images would be stored on your computer why not use the flash uploader to browse to the folder your images are stored and select them?
