Enable or disable name tags
Name tags are enabled by default in the Picasa software, which means that Picasa will use face-matching technology to scan your photos for faces. Adding name tags to these faces lets you organize your photos by the people in them. You can turn it on or off at anytime:
- In Picasa, click Tools > Options (PC) or Picasa > Preferences (Mac).
- Click the Name Tags tab.
- Toggle the 'Enable face detection' checkbox.
- Click OK.
