As a person who has always taken a great deal of pictures at sporting events and educational settings, storage and organization of these photos (and videos, but we are not going to talk about videos today!) has always been an issue. Sure, school Google Drive accounts have unlimited storage, but many of the photos that are taken pertain to family and friends. Of which, you may not want in your school account.
A relatively new Google Photos option of unlimited storage (if correct image quality settings are established) is an amazing option for storing or backing up photos from mobile devices and computers.
People obviously use an assortment of photo sharing/photo storage options, join us for Lunch N' Learn or browse the presentation to see if Google Slides meets your photo storing/sharing needs.
