The PhotoDeck-Lightroom Publish plugin allows you to:
Lightroom allows to create two different kind of collections :
In PhotoDeck, both are galleries. In Lightroom, a folder can only contain sub-galleries, not images. A Lightroom gallery can contain images, but not sub-galleries.
Therefore, to create from Lightroom a gallery that will contain sub-galleries, create a new "Folder".
Gallery synchronization doesn't match existing images in PhotoDeck with your Lightroom catalog, as there is no reliable way to achieve this: only images uploaded through this plugin will be visible in Lightroom.
Gallery synchronization is optional: when you create a gallery in Lightroom, a new PhotoDeck gallery is created only if no gallery with the same name and parent is found on your site. You can therefore simply add in Lightroom the PhotoDeck galleries you need to manage, without synchronizing the whole structure.
Gallery synchronization can be performed at any time from the PhotoDeck publish service settings.
When an image in Lightroom image is changed (metadata updated or image redeveloped), Lightroom will mark the image as needing a re-publish. Going through the corresponding gallery and hitting the "Re-publish" button will, by default, only update the metadata and not re-upload the image, as LR can't tell whether the actual pixels have changed.
If you need to re-upload the image, go to Lightroom's PhotoDeck publish service settings and check the corresponding setting. Don't forget to uncheck afterwards it if this is a one-time need!
This plugin also allows simple one-time exports, without having to publish in a gallery.
Exported images will show up in PhotoDeck under All files (they will not be visible on your website until you publish them from My Images & Videos in PhotoDeck).
This plugin is open source so any developer can keep improving it. The code is hosted on Github.
