Do you want to Post/Schedule multiple photos either to an existing Album or to the Wall? You can do that with Publer!
You don’t have to create a new Album every time you want to post multiple images.
After selecting the Facebook account you want to post to, click the Media Options icon. Click Timeline Photos and you will be able to select an existing Album. If you have selected more than one Facebook account, then you have to choose the respective Albums per each.
You can either choose Timeline Photos if you want the photo/s to be posted to the wall; select an Album you’ve already created; or create a new Album from scratch, right from the dashboard.
Don’t delete the existing Album you selected from Facebook, otherwise your scheduled photos will fail.
