Publish modified photos
A publish service differs from an export service in that it maintains an ongoing relationship between
Lightroom and the service (in this case, Flickr). If you make changes to photos that have already been
published or delete them, Lightroom attempts to mirror those changes on the service. To see this:
1. Select one of your photos that has been published and make a simple change to it (for example, rotate
the photo 90°). You will see that photo move to the "Modified" state.
2. Click Publish again.
Lightroom re-exports the photo, replacing the existing photo on the server with the new version.
N : Because of limitation in the Flickr API, Lightroom cannot replace photos on a free account. If you
OTE
attempt to do so, Lightroom ask s if you want to delete the photo and republish it.
