When to use the attribution-sharealike license? When it can help others. You might have friends who teach and are seeking images they can use in the classroom. You might receive a query from a publication. In most circumstances, why not make the image available freely to all? You are asking for a credit and mention.
Attribution is important in providing credit to creators and motivation for information sharing.
