Paul has his 50th high school reunion this week and he knows that everyone will have cell phones, taking pictures and uploading to social media. Paul wants to know how to get the images all together. Leo suggests using hashtags. If he places the hashtag all around the reunion and announces to everyone to hashtag every post, then everyone will be able to search and see them. He can also create a central shared photo album at Google Photos and invite them to the shared album.
