Some might question the usefulness of syncing because if you take a photo on your phone, it’s already easy enough to email it to friends using the Yahoo Mail app. Now by enabling photo upload, a user’s photos will be available on desktop automatically,” Albers said. “Gone are the days of having to upload a photo to the cloud or email it to yourself in order to share it with friends. Yahoo said that photos are only visible to you and those you share them with syncing can be disabled and shared photos deleted in Yahoo without affecting your phone’s camera roll.
Log into your Yahoo Mail iOS or Android app, select Settings > Photo upload, and then toggle the “Upload photos” feature to begin.
