Stupid google plus on my phone HELP!!?

[Robert]

Google+ automatically backs up images into their cloud much like google drive or drop box on android

Like other applications like Facebook they synchronise to your phones gallery via a data connection and appear in your library, these are not saved locally so if you delete images that are backed up to Google plus or Facebook etc they may still appear in your albums because you've set up sync between apps and your phone this explains why when you try to share photos outside of the app e.g. Picture message it downloads from their cloud to create a local pictire file or a temp file to then send after this is may or may not delete from your phone ans remain backup up online
