As the Account Owner, you have the option to choose where your Facebook photos are posting to in Sprout. To make this selection, go to "Business Settings" under the gear icon in the upper right hand corner of Sprout. If you would like the photos to post directly to your timeline, rather than in the Sprout Social Photos album, select "Facebook Timeline." You may post up to 10 photos per post on Facebook through Sprout.
