Shotwell le permite marcar sus fotos. Cuando se marca una foto, aparece un pequeño icono de una bandera en su esquina superior derecha. Puede seleccionar el elemento Marcada en la barra lateral para ver todas las fotos que se han marcado.

Flagging a photo marks it as special. You can interpret this in any way you like. For example, you might flag all photos which need visual adjustment, or all photos which you want to share with a friend.

Flagging is also useful because you can operate on all flagged photos as a set. For example, you can select the Flagged view and then upload all flagged photos to a publishing service.
