I would like to ask few questions:-
- How many images does the catalog from the collection have?
- Are you importing the image from an external drive or primary disk drive?
Now to answer all your questions, I would suggest take a look at Lightroom web where you can add a comment, rate, assign keywords to your images. See Learn to use Lightroom on the web
Hope that helps.
The master database has about 943315 images cataloged. The Lightroom database is on the primary drive. The original image files are distributed over 13 USB 3.0 hard drives.
When we export single photo shoots (Somewhere between 200-1500 images), we export them to USB 3.0 external drives so we can edit them and let the client rate them. Then we reimport them to the master database.
Do you have the option to turn off 'Don't Import Suspected Duplicates'? That would presumably stop the duplicate checking.
We use the function "Import from another catalog" as we only reimport the metadata and changes. So there is no "Don't Import Suspected Duplicates".@
