Thanks for the link. SmugMug now shows in my Publish Services list in Lightroom and shows my folders. Unfortunately my folders all show as empty. How can I bring my photos over?
You can do it in bulk but I recommend you start by doing a single galley at a time. The plug-in attemps to sync the photos on SmugMug with your originals in the Catalog. If you get any conflicts you need to click Match or No Match for each suggested pairing.
Go to Publish Services and right-click (control-click) on one of the gallery names with zero photos published. Choose Edit Gallery and wait for the dialog to open. Put a check-mark in the box to Sync photos and click the Edit button. You should see a progress bar in the Lightroom Library.
See this You Tube Webinar which is very detailed.
OK John...the link appears to be working again. I actually contacted Smugmug about the same time I posted here...maybe they just fixed it.
