Neither title or description are required when publishing a photo. But we strongly encourage you to describe each of your photos. Sometimes the story behind the image is much more interesting than the photo itself.
Tell us why did you take that particular photo on that particular day. Who is in the photo, where was it taken, how did you feel while taking it, and what do you like about this image.
Well described photo album will have much bigger sentimental value after one year of daily photo taking.
