You can “flag” photos to temporarily mark them. For example, you could flag a set of photos in the same way that you might sort through a stack of snapshots, setting aside your favorites to get reprints or put in an album.
To flag photos:
Click to select Events or Photos in the Source list.
If you selected Events, select the Event you want, and then double-click it to open it.
Select the photo or photos you want to flag.
Choose Photos > Flag Photo.
A flag icon appears on each photo thumbnail. In the Source list, the number of flagged photos appears.
To see all your flagged photos, select Flagged in the Source list.
To remove the flag from selected photos:
Select the photo or photos and choose Photos > Unflag Photo.
To remove the flag from all flagged photos:
Do one of the following:
Select Flagged in the Source list, and then click the Clear Flagged button in the top-right corner of the window.
In the Source list, move your pointer over the number next to “Flagged,” click the X, and then click Clear in the dialog that appears.
You can create a new Event from flagged photos, or move flagged photos from their current Event to another existing Event.
