The first thing to do is download the Google Photos app if you don’t already have it on your phone. To create a shared album go to the Albums tab, tap Shared, and tap the green plus (+) button.

You will have to select at least one photo to create the album. Make your selection and tap Next. You’ll be prompted to give the album a name after which you can tap the Share button to invite others to your album using their names, phone numbers, or email addresses. Anyone you invite to the album will receive an email or text with a link they will have to click in order to be able to view and add photos.
