Sync Smugmug uploads between mobile and master catalogs in Lightroom
OK, here's what I'm trying to do.
I'm using two catalogs... a "mobile" catalog on the computer that's always with me, and a "master" catalog on an external drive that I usually leave at home.
When I'm out and about, I process a few photos, keyword them, upload to SM. When I get back, I import the photos from the mobile catalog to the master catalog, and everything I've uploaded shows as "New Photos to Publish" in the Smugmug exporter.
I can't figure out how to tell the master catalog to sync the photos already on Smugmug, and now also in the catalog, so they don't egister as duplicates.
Any help would be appreciated.
