The album type defines where photos show up.

Art

  • Tapestry (global gallery of community art).
  • Home widgets / discover artists.
  • General wall (not mixed with likes and comments from “My circle”).

Social

  • My circle wall (includes likes and comments on those photos).
  • Not listed in the tapestry or home widgets.

So the product is called “Art” and “Social”: it is not just a style label, it is a visibility and product filter.
