You can add a title and description to any photo you've posted (except your "now" and "then" profile photos).
To add or edit photo titles and descriptions:
For desktop users, click My Classmates® in the top portion of any page. (For mobile users, click , you may have to expand to make your selection), go to My Profile, click the Gallery tab, and then click on any of the individual photo thumbnails to enlarge the photo. If using a computer, you'll see the option to Add Title and Add Description (or Edit content that's already there) on the right side of each photo. If using a mobile version of Classmates, you’ll see the option to Add Title and Add Description (or Edit content that’s already there) below each photo.
When you're creating a new photo album, you'll see fields to enter an album title and description. To edit those later, return to My Profile, click Gallery, then select Album View. Click the pencil icon next to an album to edit its title and/or description.
Note: The only profile albums you can't edit are your default named album ("Xxx's Photo Album") and your album of Tagged photos. If for any reason you don't want those to show to other members, simply delete all of the photos they contain.
