How can you add photos to an existing Person, Place or Event?

What will be an ideal response?

To add photos to an existing Person, Place, or Event from the Organizer, select the
photos you wish to include, and then either drag the selection from the Media Browser
to the desired tag in the Tags panel, or drag the tag itself to any of the selected images.
To add photos to an established Event from the Events view, double-click the Event
stack to expand it; then, click the Add Media button in the Taskbar at the bottom of
the workspace, and browse for the photos you wish to add. In the People view, double
click to expand a person's stack, and then click the Find More button in the Taskbar.
