Tags are descriptors that can be used to further organize your photos as well as provide more context for the photo. Tagging photos is a way to help you to look for specific people, places, events or other characteristics that are important to you. They can be as broad (i.e. "graduation" or "holiday"), specific (i.e. "2019 graduations" or "New Year's Day"), or anything in-between (i.e. "high school graduation" or "fall holidays").
Tags are different from Albums in that you cannot organize within the Tag.
Here's some helpful articles to get you started:
- Uploading Photos and Documents directly to a Tag
- Sharing Tags
- Downloading a Tag
