What is a photo “tag”?
Tagging is a neat way to add a keyword or two (or more) to a photo that describes it in a qualitative way. For instance, if my photo was of my dog was playing Frisbee on the beach, I might tag the photo “beach, frisbee, gordon setter, sun.” Or, if my cat was sitting on a table next to a vase of red roses, I might tag that photo “red, roses”.
