The Thumbnail View is the primary view of all the photographs in the selected directory. The photograph’s thumbnail, filename and rating are grouped together to form a stamp.

Navigating
Navigating the Thumbnail View is done via mouse wheel and key input. See navigation section below.
Rating Stamps
Each stamp can be given a star rating of one to five stars, or no rating. Click on the star rating to change it. You can also use the keys (0-5) to select the rating for all selected thumbnails.
Rating a stamp with the same rating it currently has will unrate it. For example, if there is an unrated stamp and you rate it a 3 by clicking 3 or select the 3 stamp, it will be rated 3. If you the rate the same stamp a 3, it will set the stamp to unrated. Hitting the ‘0’ key will also set the stamp to unrated.
To rate multiple stamps, select the stamps you want to rate, then press the rating (0-5).
LMB on a stamp’s star, when multiple stamps are selected, only sets stamp rating clicked on.
