Karen Wong has a great post about one of the coolest new features to Windows Live Photo Gallery: photo acquisition. Yesh! Photo acquisition can be cool. There's a step where, looking at time groupings, we help to put your photos together in groups that make sense.

For instance, say on this coming Saturday, you first take some shots of the morning sun hitting dew sparkling in a spider's web, followed later by some lunchtime shots of fruit at the farmers market, and then you end your photography for the day with some snaps of the sunset. When you import your photos with WLPG, we'll group these three events together and you can name them and tag them uniquely right there.

Nice.

One principal thing for you to know about this:

Previously Imported Items
We know that a lot of users don’t delete their photos/videos on their camera after importing.  In the Vista photo gallery, we automatically detected items that were already imported into the gallery, and did not import them again to eliminate duplicates.  In Live, we will show these items in the ‘Review, organize, and group items to import’ option, but by default they will be unchecked.  You can go ahead and check these items if you’d like to re-import them into your gallery.

In this case, you might see the text "There are 0 new items to import" just because you've already imported everything. But like Karen says, you can re-import them by checking the group.
