I seem to have loaded my photos onto Photoshop.com from both of my computers. The photos on both computers are the same. I have now turned off sync/backup on one computer. How do I eliminate the duplicate photos from Photoshop.com from that computer?
Please confirm is your catalog is been categorized in to albums,
If so go to photoshop elements preferences (Edit>Preferences>Backup/sunch) and uncheck those albums which are already present on PS.com.
And start the back synch again.
