Change a photo’s information
Select the photo.
Click the Info button.
Click the title or description field, and then type the new information.
You can add a photo title, description, and the date and time a photo was taken, if your camera didn’t record it. (Your camera also assigns each photo a filename, which you can’t change.)
Important: Editing a photo’s information changes it in the photo library and in all albums, projects, and slideshows where it appears.
Select the photo.
Click the Info button.
Click the title or description field, and then type the new information.
Tip: To change the title, date, or description for multiple photos at once, select the photos and choose Photos > Batch Change. Then choose your options from the pop-up menus and click OK.
