This Picasa tutorial will now show you how to launch Picasa and tag people that appear in your photos and images.
Picasa can be launched using the Windows Start menu. look under All Programs and select Picasa 3.
When the program first starts it begins to search for and index all the images found on your computer. When it is done you can create additional albums sorted by people, date, and other attributes. Your folders and albums are on the left, the contents of the folders and albums are in the center, and the ability to tag the people in each image is found on the right.
You may be surprised at the power Picasa brings to the table in the form of free software. After you tag a face with a name, the software will automatically begin to identify other photos that contain the same person. You, the user, can confirm the contents of each photo and the program will continue to learn to identify the different faces it encounters.
To tag a photo, select a photo in the center panel. You will see the face from the photo appear in the People panel on the right.
In the Add a name field, type in the name of the person in the photo. If the name has been used before or is in the Picasa database, you will see it begin to automatically suggest it as you type.
You can also use the Unnamed people folder to quickly tag a large number of photos.
Your photo will now automatically become a member of a folder bearing that person's name.
