Scenario
Mother (passive user) wants to find pictures from her son's 6th birthday so the grandparents can view it. She is not sure where these picture are stored- if it is on a site, a camera, or anywhere. So she searches on the site for them. It isn’t there, so she tells her husband to upload it from their camera. Once she gains access to it on the site, she distributes the picture (as well as maybe any other relevant ones) to the grandparents.
Goal: share a picture from son's 6th birthday
